Best audiophile switch

Your disagreement may be due to semantics. I agree with @Synaxis that fiber can still impart a flavor on the sound. When the music is robbed of color that is still a coloration from my perspective. When the highs are made to sound harsh and unnatural, that is also a coloration from my perspective.
Yes, there is a misunderstanding of terms. I use "coloured" in reference to tonality. Not to say that there's any actual frequency response deviation, but there are often obvious tonal shifts.
I'm not sure though how meaningful the term "performance" is when describing sound quality. I'm not sure what you are even meaning to convey with this.
The differences I hear with different SFPs are in high frequency cleanliness, soundstage size and instrument separation. The switch or FMC has a greater impact than the SFP.
I tend to look at hardware more from the perspective of how well it gets out of the way of the music.
In order of most to least importance, I listen for musicality, tonality, detail and soundstage.

The fiber optimizations that I had implemented a while back achieved that far better any copper that I had tried up to that point. A copper cable that I tried not too long (QSA Lanedri Gamma Infinity) proved to be significantly better at getting out of the way of the music than my fiber.
I don't doubt that, an ethernet cable can be just the ticket for the sound you want. But I use ethernet in conjunction with LAN cables. Can you please describe your network? Any long runs? What fiber gear did the QSA replace?

Some commentary about this can be found in this post (and the links he shared). All three of us heard the same thing. The fiber span is about 8m long with a Sonore opticalModule (original) at one end and the EtherRegen at the other. SFPs are Finisar though I don't recall which model. The QSA-L cable was long enough to allow us to bypass this span of fiber all together.
 
I see where you're coming from and I don’t want to get caught up in semantics, but to be honest, 'gets out of the way of the music' isn’t entirely clear. How colorless can music be? How can we ever know if we’ve truly heard it that way?
This isn’t difficult to ascertain when performing comparisons. Does the switch make a piano
or drum or voice sound more or less like the real thing? Super easy to determine if that has been the objective all along when assembling a system.

Your phrasing suggests 'removing elements' from the conditioned signal to get back to the original sound quality (by adding a QSA Ethernet cable), while others here may see it as adding something to get closer to the desired outcome—perhaps achieving 'transparency' or 'neutrality' (if that's the goal).
I was simply pointing out that the disagreement could have to do with semantics as people may have different meanings when they apply the term “colored”. That was confirmed.

I then shared how I tend to look at things, which perhaps avoids the term “colored” by saying if something gets in the way of the music it should be avoided. A coloration is one way a component or cable can get in the way of the music. There are others too.

Ultimately, we're discussing the best switch—one that alters noise in a way we appreciate, much like the DAC, streamer, and cables we use.
My goals are best met with the switch that best gets out of the way of the music. How it does that, doesn’t matter to me. I just want to hear voices and instruments soundimg more like the real thing.

That said, this thread is about audiophile switches, and we seem to agree that a switch can’t be judged in isolation—no audio device can. The key is understanding how it interacts with cables, power, and connected gear.
I am not sure my understanding mattered all that much in my determination of which switch sounded best when we did the validation experiments described in this post. Keith linked to a post from Jeremy who was also present. Quoting Jeremy:

One thing I have always appreciated about Ken's system across its many evolutions (a handful of which I've been privy to) is that his focus on timing and precision makes it an excellent lens to experience music through. When you plug something new into his system, it's very 'what you hear is what you get' -- not that it's perfect (no system is), but that the relative strengths of whatever gear or cabling you insert are evident in some form. In other words, it doesn't take effort to hear a difference when there's a difference to be heard.”

That, I think, resulted from my “gets out of the way of the music” approach. Interactions can still matter, but probably far less than from following the approach of balancing interactions that many others follow where a component or cable is chosen because it helps arrive at the balance they desire. Interactions are far more influential with that approach. For example, if one selected an Ethernet cable to bring more bass, to balance out a switch that robbed from the bass, swapping to another switch might also require selecting a different Ethernet cable. But if the Ethernet cable was selected because it did the best job of making a pianist sound real, it will make more evident how well a switch change helps or harms that.

Some thoughts:
- The oMD v2 is reputed to be quite an upgrade over the original
- I'm not convinced an external clock is a good idea. People I respect say no, and any measurements I've seen show deteriorated technical performance. (OTOH, I've never heard one.)
- No mention of PSU on the ER or oMD
- Unknown Finisars - Lots of people using the FTLX1475D3BTL, the priciest Finisar, but IME incompatible with the ER. Works great everywhere else I tried it (oMD v2, MikroTik CRS-305, Intel NIC). I suspect the Finisar 1471, which many others use, is also a problem in the ER due to SFP+ heat load. I use the FTLX1475D3BTL in my oMDv2 and FTLF1318P3BTL in the ER.
- QSA Lanedri Gamma Infinity ethernet cable; $4000 for 3m, so ~$10,000 for 8m in your system. Not for everyone, especially me with a 15m run.

Anyway, I'm sure your system sounds great. You obviously put a lot of care into your choices. Systems and personal preferences differ, especially in network audio, where everyone is in learning mode.

Dan, all great points and find that many have lower performing SFP and FMC in the chain. Not saying that is the case for Kenny but he did not detail what SFP were used in their test. Also I can attest that the oMD V1 is not on the same performance level of the v2.3

But maybe to you that sounds the same as:

We all want that, no? Or:
simply assembling a system that sounds good to ME.
I could not have said it better. Great points.
Again, this is NOT aimed at you,
I know it is not; you only quoted a couple words from my paragraph, reminding you of a familiar statement. While I tried juxtaposing two different ways of approaching how we want to hear our music, resulting in choosing the best switch—one that alters noise in a way we appreciate. :)

Yes, I’ve heard that. I have no plans to upgrade as my next move on networking will be to snag a QSA Lanedri Gamma Infinity. I’m hoping they go on sale again.

The upgrade to bring my REF10 to SE120 level improved the sound quality more than just adding the clock in the first place. What most surprised me was how it made it difficult to hear a difference with my fiber span powered down. Prior to that, powering down would bring a noticeable uptick in sound quality. I honestly think that most people who produce measurements are intentionally trying to show deteriorated performance.

Farad Super3 on the ER and inexpensive Chinese linear supply with an outboard regulator on the OM.

I don’t own one - it was a friend who brought it over. He purchased it while they were on sale. Sale price was essentially the price of the Gamma Revelation. The magnitude of improvement was on par with what one gets from a really good switch though one still needs a good switch to get the best from it.

Well said!

You asked that in response to me writing that “I just want to hear voices and instruments soundimg more like the real thing.” My answer to your question is no. Many who consider themselves audiophiles care about this, but many don’t. Those that don’t tend to want sound that’s pleasing to them. Or alternatively, they don’t listen to music that features analog instruments so “real” has little meaning to them.

Interestingly enough I am now evaluating a set of Bluetooth headphones (B&W Px8). They give up the realism I get from my main mobile solution, but I love the convenience so I am inclined to sacrifice realism for pleasing to listen to. That they are.

Thanks. I think since your system is built to present recordings exactly as they are, only a limited selection—those that capture real instruments and voices with true transparency—will sound as intended. Anything that falls short of that standard won’t be as enjoyable; instead, its flaws (or exaggerations/colourations) will be fully exposed. In a way, that makes your system deeply rewarding with the right recordings—but also quite unforgiving with most others. Does that make sense to you?

It’s fascinating how, despite your pursuit of pure realism in your main system, you're willing to set that aside for convenience when it comes to mobile listening. I appreciate the ‘confession’—it’s a reminder that, in the end, enjoyment matters just as much as the real thing.

I’ve been a music lover/collector and audiophile for 50 years (age 12 to 62), and the arc of achieving system transparency and realism (with acoustic instruments and voices) has unavoidably always bent towards revealing the lack of depth and dynamics of lesser (the majority of) recordings.

My wife and I are always disappointed when recordings of most of our favorite artists come across as flat, uneven, or just downright barely listenable on my system. And yet many natural (recorded in a real space) older recordings will sound glorious and uncanny.

That said, I find that despite exposing the flaws of compromised recordings, my system always allows for greater connection and understanding of the artists’ expressions.
I surely would not want to go backwards.

Lastly, I have always found that any system change which makes the presentation of different recordings all sound similar (even if enticing) is the WRONG direction.
A change that reveals each recording to have its own unique presentation (depth, air, tonality, instrumental interplay, etc.) is the RIGHT direction.

Just my $0.05…. ;)

Improving my source and improving the cabling has been the rising tide that has lifted all boats. The last few improvements have made it so that I can better enjoy just about every recording in my library.

I believe It’s not so much the warts in a recording that make the recording difficult to listen to, it’s how one’s system and room react to those warts. Consider massed strings that have a harsh edge. Noise and grain added the cabling or components can accentuate that edge and color it in a way that makes one wince. Reduce that noise and grain and those mass strings sound more like the real thing.

Certainly networking improvements have helped here as well. Everything matters so making sure that everything that is selected gets out of the way of the music as best as it can for one’s dollar can make one’s system much more enjoyable across varying levels of recording quality.

That cable is Belden Blue Jeans CAT6a with REVConnect plugs added. You can get 15m from BBJ for under $100, those plugs add $15. So save yourself $9,900 and buy me a drink next time you’re in the UK.

I’ve been using it for years. I also have the Belden 5T00UP speaker cable QSA use, my 5m pair cost about $200.
 
When I first got into this hobby the better my system got the worse flawed recordings sounded. That was until I started optimising the power, grounding, isolation and cable side of things. i.e the REAL source first. Those not into such tweaking don’t know their system is being held back so drastically.

I think you’re on to something important here.

Have you directly compared the QSA Lanedri Gamma Infinity to the Belden BBJ with REVConnect plugs in a properly resolving system? If not, then your claim is pure assumption, not experience.

You expressed well what I was trying to get across above.

As far as not knowing how badly one’s system is being held back, I was most profoundly awoken to this when I head what ASC Tube traps could do when a stack was placed in the two front corners of my listening room. What they do is dry up what ASC refers to as “head end ringing.” Ideally the only sound waves that should hit our ears is those that emerge from our speakers, but what we actually get is sound bounced off our walls arriving slightly delayed. This can harm the music in ways that could be far more detrimental than the harm done by power, grounding, isolation and cabling. Amazing what happens though when the room-induced ringing is soaked up. I kicked myself for not taking that more seriously years prior.

Or spend the right amount of money on QSA-Lanedri cables so you can get a good laugh at posts from people who think it’s helpful to offer an opinion on a product they’ve not tried themselves.

I have three Belden CAT6a cables from Blue Jeans Cables. They are nothing special; compressed soundstage, dark sounding, lacking microdetail. Nicely built and come with individual certification. I'm happy to have them, but I can't use them in my main audio system.

No QSA-Lanedri for me. My next purchase will be an EtherRegen v2.

The UK's QSA (fuses) dealer, Futureshop, is 10 minutes from my home and wouldn't do a QSA loan or blind test, and I'm a long time customer. I did ask the QSA cable guy about a loan and he said I needed to buy i.e. import and pay 20% tax that I would never get back, even if I returned the product, and trust him for a refund. I only buy from UK businesses, we have good consumer protection.

I recall he also said there was a collaboration with Belden on the cable design. Untrue. I asked Galen Gareis. Belden do special orders with own label wrap and REVConnects instead of plastic connectors, but it's the same Belden cable underneath. They don't make special cable for anyone.

Futureshop are a very large business. Besides the fact they sell QSA, I like them. They supplied me with 25m shielded copper ethernet, Audioquest Pearl CAT7 to the hifi and a Supra CAT8 to the AV. They prepared a guide here. Basically al that matters is speed (irrelevant for audio), insulation and don't physically damage the cable or connectors.
As QSA CAT6a is physically exactly the same as factory supplied Belden CAT6a with REVConnects, it will perform exactly the same.

I have three Belden CAT6a cables from Blue Jeans Cables. They are nothing special; compressed soundstage, dark sounding, lacking microdetail. Nicely built and come with individual certification, but I only use them in non-critical locations.
I despair when I read attribution of essentially analogue characteristics of sound reproduction to error-checked coded packet data sent over a network. I thought this had been put to bed a long time ago and that the issue with networking is not the data, but electrical and EMI/RF noise that the hardware might bring with it.
