i won’t hijack the thread, but will mention the TRP3 will be getting professionally powder coated by a good friend of mine. This will be its new color, sans logos lol. Going for a super creamy pearl white, and doing the case, front panel and knob all the same. I’ll post when finished in a few weeks.
I am on business travel, but have this below on my phone. I was considering replacing the rectifier adapter with a matching wood type same as the quad, but with a new automotive paint job coming for the TRP3, I think the Zebrawood(?) will look better. If anyone is looking for a pair or a quad of...
Yes, I am using a TP adapter with the RGN2004 (P8A socket). The Horizon thread on here has quite a bit of feedback on the sonics of the RGN2004.
Thanks for the Puritan info. I hadn’t heard of them before, so I’ll check them out.
I’ve also ordered the TP silver star grounding cable from @takacs75 and can’t wait to see what improvement that will bring.
There is no grounding lug on the back of the TRP3, so I was considering the Entreq grounding boxes. Does anyone have any experience with them they can share?
I am...
For about 8 months, I have had a TRP3 with some a la carte GA3 upgrades that I added to it during the production build. It is basically the GA3 w/o the gold finish and flight case.
During those 8 months, I’ve gone through several tube rolling exercises, and thanks to this and other threads on...
I just received the TP adapters that @Bblock recommended in post #2306. They’re about 4 hours in and I already notice a more sophisticated (?) presentation of the music. Like it’s a little more mature or went to finishing school. I would agree with @Bbock’s assessment that there’s more clarity...

While I understand the need for attenuation is system specific, and not necessarily a requirement for everyone, they have made a huge impact with what’s being sent from the Lampi to the amps.
The SR Purple fuses are specific to the M750s however, and as long as you orient them the...

@tmallin, congratulations on finding the right sound for your system! I’m sure the Benchmarks sound exceptional based on your description above.
I wanted to return to this thread with an update on my AVA DVA M750 amps. I won’t post anymore on this thread after this unless it is relevant to...
I did a quick google search, but it turned up everything from bike frames to test tubes. Do you have a link to the TP adapters? Would love to check them out.
Since this thread is getting a little more action lately, I’d like to ask what tube combinations are hot right now in the TRP?
Following this thread, and through some trial and error, I’ve settled on the Sophia Aqua II for the regulator and a quad of Siemens F2A for the output tubes.
Anyone...
So, I have a TRP 3 w/E11. Both the build sheet and the rear plate say TRP 3. But the info above indicates it may now be the TRP 4? There is probably some thing(s) that are indeed different within a true, badged TRP 4, but I haven’t seen anything specific yet.
Here’s another review from PF a couple days ago. The M750s seem to hold their own against Pass XA-30.8 Class A amps.
The reviewer mentions the same issue I had with the speaker terminals rotating while loosening/tightening. It’s a quick fix (just needs a little extra tightening), but maybe...
I’ve been on a path to replace my vintage Jolida JD502 tube integrated amplifier for a year or so. It’s been re-capped, had resistors changed, and holds bias perfectly. It is currently powered by GL KT88 output tubes (sometimes swapped for TungSol KT-120s), and using NOS JAN-GE 12AX7WA and NOS...
Interesting… I had a very slight hum from one of the DVA 750s as well. It actually came from the amp chassis, but didn’t present in the speaker it was connected to. I was using the original, provided AC power cord (a new Cardas was on order but hadn’t arrived yet). Once I swapped to a higher...
I purchased a pair of DVA M750 monos a couple weeks ago. Should be here this weekend. I am looking forward to hearing how they sound, especially since I’ve been following your journey with the M225’s and now the M750s.
Thank you for the updates! I’ll post with impressions as soon as possible...
To clarify, my DAC wasn’t shipped with the Aqua II, I purchased it separately. The TRP 3 was delivered with a NOS Svetlana 5C3S. You also went the Golden Atlantic route, which I believe includes better tubes than the non GA version.
The Aquas are easy to differentiate, the Aqua “I” has really...
Quick update on the Sophia Aqua II saga…
I posted a couple months ago about a brand new Aqua II 274B basically melting my previous Baltic 3. Lampi serviced it and offered an upgrade path that I thought was incredibly fair. I also posted about the custom upgrades to the TRP 3, and I’ve been very...
I voiced my expectation vs reality to Rob back in August when I received the TRP. I don’t think it’s any sort of mis-advertising or anything, and quite frankly it could be made out of old cardboard as long as it sounds as amazing as it does (and it DOES!), but the pictures of other Sahara Silver...
Yep, Sahara Silver, both faceplate and chassis cover. The only difference is the knob is a different finish, more pearlescent. Honestly, I’m not that keen on the way the Sahara Silver looks. The color/sheen on the TRP looks nothing like the pics of the Horizon in Sahara Silver, which is what I...
No kidding! It was ever so slightly touching, probably less than a mm of the spade just barely touching the other post, but enough to be slightly noticeable at higher volume and with greater dynamic swings. It was enough to steal some upper end purity from the final output, so it was really two...
Quick update after a week. I was on travel for half of last week, but did have a chance to put about 70 total hrs of music through the new TRP3, and have some more observations to share.
Before that though, I had a “lightbulb” moment early last week. I had mentioned the slightest bit of a hot...
@Golum The Siemens F2A tubes are spectacular in the TRP3! Using them with the new Aqua II 274B and a SR Master fuse. I’ve only got about 40 hrs on all of it, but it is a significant upgrade over the B3 w/E53 so far.
My TRP3 VC/Balanced arrived last week! I was going to let it burn in on the stock tubes (Shuguang 5C3S and 6550B quad), but true to form, I had the supplied tubes and fuse swapped out within the first hour of it being powered up lol.
So any observations on sound differences moving forward will...
Yep, I wish the B3 didn’t have to go off for repair, but I am very happy about the upgrade! It’s going to be all Sahara Silver (front/top/sides) which looks spectacular on the Horizon. Really excited to see how it turns out on the A3 with the large VC OLED panel!
Nice! I’d love to hear your thoughts on the Aqua II when you’ve had a chance to figure it out.
That’s a good group of rectifier tubes. I also have a Tungsram P200/600 here, but still waiting on the adapter (and the A3 TRP) to try it out.
I don’t have apples to apples insight to offer, but I’ve tinkered with some variants mentioned above.
I had a Baltic 3 (balanced, volume control, Engine 53) that I initially purchased an EML 274B for. I pretty quickly settled into some KenRad VT231 smoked glass and Brimar CV4003 tubes as well...
Based on your recommendation (and others) I just purchased a pair of NOS Siemens F2A tubes/adapters as well as a NOS Tungsram PV200/600 w/ adapter. Should all arrive by end of August or early Sept.
My A3 Balanced won’t be here until late Aug also, and I’ll let it burn in on whatever tubes are...
I’m still in the process of putting in work and reading through this ENTIRE thread when time permits. Currently on Page 64 after starting over from the original Page 100 I jumped in on. What a fantastic thread so far, btw!!
It seems both of our questions were answered by Lukasz himself on Page...
