Most Important When Setting Up A World Class System— Prioritizing Subjective or Objective Criteria?

[Ted Denney III]

Dammit, Charles, I’m just about to leave the house to go on a motorcycle ride, but you’ve pulled me in! My PowerCell 8SX will deliver all the current your amplifiers need—unless your amps actually require 20A because that’s what they’re pulling from the wall. None of the PowerCells will impede wall current. The PowerCell 14 gets close to the PowerCell SRX in subjective performance improvement, though it lacks the SRX’s 20 outlets.

 

[Charles S]

Ted, I know how you must feel. I'll be roller skating at Rivergate during the Super Bowl. I skate for 3 hours with maybe at most three 10-minute diet coke breaks, so I'll miss most of the game. I begin my preparations at around 6:30 cst to be on the floor at around 8:15. Skate lasts until 11:30.

So, I'm going to choose your SRX XL line for two reasons. It's your thread and if I had the budget, your gear would very likely be the gear I would choose. I'll let you or my dealer decide the conditioners.

Next would be the speakers. That's easy for me. My choice will be the Wilson XVX with dual Subsonics which means 4 extremely powerful mono amps. My amps will be the brand new MC2.1KW's and I will need four of them. Since they are only 50K a piece they are a bargain, and this allows me great flexibility with my wires. McIntosh sounds superb with solid silver. I'm a great believer in silver wires that are absolutely topline, and your gear would fit my bill perfectly and the Mac gear will keep costs under control. I would want 7 20-amp lines and 7 power conditioners (your choice) with appropriate speaker cables and balanced IC's. One for each XVX and two for each Subsonic so that for the Subsonic, each 1,000-watt power module had its own conditioner and 20-amp line. They are quite inefficient. Everything will be run off the 4-ohm taps. One power conditioner for the pre and sources to make seven.

Next will be the preamp and sources. Again, that's easy for me. My choice will be the C-12000 and the MCD12000. Why? Because I know what the gear sounds like and I love the tube sound they impart to all my music. No solid-state DAC or preamp can match it or duplicate it. It's a well-kept secret how good McIntosh sounds with solid silver and because of the relative cost of the Mac gear, I can utilize your gear to the fullest and still stay well within a reasonable budget.

If you noticed, I don't do vinyl. it's way too much trouble and expense. The above system will have superb resolution and sound analog simultaneously. You manufacture the full gamut of gear that I would want. Just go to your website and pick out my gear for me for isolation, passive room treatments, footers, etc. It's like going into a candy store for me, and the cost savings of no ultra expensive turntable and arm, no gazillion dollar 5 component DAC, and 300K mono amps, and 170K pre's, etc. make my world class system come in at I estimate at around one million.

The only thing I would add is a pair of MC3500's, if I could have absolutely everything I wanted. They would sit adjacent to my 2.1KWs for my XVX and I'd just change out the connections. Wouldn't take 20 minutes. Then I could run all tube to my XVX and solid state to my Subsonics, if I want. .

Folks that use Subsonics usually don't supply them with nearly enough power. These subs will absolutely need one 2.1KW per channel and the wires will need to be of the same quality as the mains. Again, the relative cost of the Mac gear to the ultra-high end like Vitus, Gryphon, CH-Precision, or dCS, make full utilization of your superb gear possible at a reasonable cost. The subwoofer system runs independently of the XVX. The XVX runs full range.

One last thing, I'm a great believer in synergy and sonic signatures. If you noticed all I have basically done is replace my AQ with Synergistic. You have an absolutely amazing website. You make literally everything that anyone could possibly imagine and it's handmade, imbued with silver, and made in CA. Although I have never heard of you, it can't be a coincidence that your name is Synergistic because you make the whole shebang. My world class system will be entirely handmade in the USA, by McIntosh, Wilson, and Synergistic.

Although your system is far from anything similar to mine. I'm interested in what you think of SR power conditioners.

Charles, who is your dealer? I’ll play along, and if you’d like, I can get involved in dialing in your system. Not as your hypocritical scenario, but because this sort of thing is right up my alley. As for power requirements, even with all those amps, I can’t imagine you’re drawing 20A. So we would need to analyze whether the trade-off of having multiple circuits is needed for current, versus the performance hit you take by having ever-so-slightly out-of-phase alignment and differential between multiple circuits.

One PowerCell SRX could handle your entire system, provided you need only 20 outlets. We could also plug the PowerCell SRX line conditioner into 2 x 20A circuits, as it has two SRX XL power cords feeding it. Running AC from two dedicated circuits through the series of multiple EM cells in the PowerCell SRX would serve to stabilize any phase misalignment differences between the two circuits. You will definitely not need more than 40A.

Send me a PM if interested. It would also be fun to make a video of your system. This is a project I’m excited about, and not because it’s a high-dollar system, but because it’s a mind walk that would be fun to take on, and promote.

How do you measure phase alignment between 2 branch circuits?

I have not been able to prove 1 phase is better than using both. I recommend it out of what appears correct. I wonder if the relationship of voltage to the neutral, and nuetral to ground causes issues if 2 phases are used and the voltage is always different between the phases. Does that allow an imbalance on the neutral/ ground that can allow mV potential on chassis.

If everything is on 1 phase and all your branches are 10awg, I don't see how the phases is different between the branches. Assuming nothing radical like one branch to a amp 5 feet and another branch to an amp 60 feet.

What I do see and easily measure is the distortion to the wave form from an amps power supply grabbing power as quick as it can, then the caps slamming shut. It drags the front edge down and severly distorts the power waveform. It cause all sorts of 3rd and 5th harmonics. Oddly some filters like Shunyata distort the sine wave on the branch circuit feeding it with 3rd 5th and 7th harmonics far worse than any amp. And I have never seen any filter that operates at 180 or 300 hert. They all start around 10,000. Low order harmonics walk right through all power filters.

The panel feeding the branches and individual branches seem to knock down a lot of the low order harmonic from traveling up the other branches. Hence I recommend multiple branch wires to a rack.

On paper, 40 watts and 2 brach circuits seem like enough power. But so do 12awg branch wire. I would spend time and money getting aluminum out of the panels and feeders and optimizing the branch wires in the panel first. Then compare a filter to no filters on the amps.

There is also merrit to a large isolation transformer with mltiple branchs from it to the rack. I know of at least 3 world class systems set up that way. And I have compared an isolation transformer to many filters and prefer them on amps. Front end can be a toss up and user preference.

I have never heard dual circuits sounding better, let alone as good as a single circuit for a stereo, unless the electronics draw more than 20 amps. If it's not down to a differential on some minute level between two different circuits, then I don't care about the reason. A single circuit sounds MUCH better when all else is correct in the system setup. Having said that, people who view proper system setup as being down to impedance-matched components where the amplifiers are more than objectively up to the task of driving a particular pair of speakers that themselves are absolutely properly placed in relation to the seating position and with the acoustics well sorted from a measurement standpoint, such people never have what I would consider world-class sound or a system that soundstages exceptionally well, with transparent frequency response from top to bottom, excellent dynamics and low-frequency control, or a living, breathing, you-are-there presentation. Never ever. The aforementioned is where we start when tuning a system for a tradeshow and the before all the obviously factors are sorted, and where we end up is a NIGHT AND DAY DIFFERENCE. So perhaps they are taking in something that the hit from dual or more circuits is below the threshold of their system and, therefore, unnoticeable.

You did not answer the question. If your running multiple circuits, all on the same phase, how do you measure a difference in phase angle between 2 legs.

I don't see the phase being misaligned unless there was a radical difference in cable length. Electricity moves at about half the speed of light as it rises up and creates the field around the conductor. If this created a timing issue with phase angle, I can't see it impacting a stereo. Other issues would be magnitudes greater at impacting sonics. A simple footer would be far more notable.

I have heard multiple circuits better a single circuit. Especially with high power amps.

I have never heard a ground loop from multiple circuits. If you run them incorrectly in the wall you will impart voltage onto the ground through EMF. But I see more issues with voltage on the ground that is from the circuit traces in the equipment itself inducing voltage onto the ground that becomes hum.

I'm sure your filter using 2 legs to power it, in essence 2 filters, will power the Mcintosh amps. I would still put the front end on a separate circuit and the digital on another circuit

And I would make sure to put the modem and router at the demarcation into the home on a dedicated circuit, same phase as the audio. And I would probably use a filter there too.

And I would Caig G100 Deoxit every wire termination from the grounds at the home, service wires in the panel, branch wires to duplex in the wall. You can more easily toss filters and cables at a stereo, but you should adress the power at the service to the rack throughly if your trying to have good power.

 

[microstrip]

I have not been able to prove 1 phase is better than using both.

It will probably depend on system characteristics. One thing is sure - ground loops will be larger with two independent circuits. But noise paths for noise created by equipment to enter other equipment are shorter with common mains.

I recommend it out of what appears correct. I wonder if the relationship of voltage to the neutral, and nuetral to ground causes issues if 2 phases are used and the voltage is always different between the phases. Does that allow an imbalance on the neutral/ ground that can allow mV potential on chassis.

Neutral and phase are theoretically insulated from ground, although some mains filters installed in equipment have capacitors connecting them to ground.

If everything is on 1 phase and all your branches are 10awg, I don't see how the phases is different between the branches. Assuming nothing radical like one branch to a amp 5 feet and another branch to an amp 60 feet.

I like my Torus ToT Max on all of the digital devices.

 

[Kingrex]

I am a Torus dealer. The only product I carry that is not a panel I prepare for client. Simply because they work so well. And they are a perfect marriage with one of my distribution panels following a single high current core. And, the NEC, because of all the solar inverters that are 120 volt now, allows me to use a SqD NQ panelboard I have optimized as all copper to distribute the power. In the past a panel rated 120/240, as they all are, had to have both A and B phase brought to them. Now I can bring a single phase leg to the panel and attach a phenalic label stating 120 volt only. Do not use any 240 volt circuits. I can attach a massive, very clean, 60 to 140 Amp core to a panel and have virtually limitless power to run the most aggressive of systems. 4 x 1.2kw amps are nothing. Thats a 40A load at peak power. I can have 3.5 times the power in reserve. That is how my system is powered.
