The 7+ was only in the PS Audio Quintet. Everything but my amp goes into the Quintet. The amp is a 30 year old Bryston 4B I sent back to Bryston to recap and bring up to 4B ST status, it has the curly, non-removeable power cord.

Both the Quintet and amp get plugged into a hospital grade Leviton outlet.

The 7+ was swapped back and forth with my diy power cord. That was were the amazing difference was, all the benefits I spoke of arose when the 7+ went into the Quintet in place of my diy pc.

Just for curiosity's sake, I briefly took the 12+ off the dac and used it to connect the Quintet to the Leviton. Again, the TWL family sound was there, but lost a little grunt.

Since eveything but the amp goes into the Quintet, I can't point to one specific piece of gear that most benefited. Since the most amazing change was the re-centering of the soundstage I would have to guess the must be a great synergy between the Purity Preamp and power as supplied by the TWL. Same must have been happening for the Rega Apollo cdp. It really was a 'grab you by the lapels and slap you in the face' difference, I can't explain it.

The diy pc was no slouch, a quality cable, albeit 10 year old technology, and upper mid-tier hospital-grade connectors at each end. Last night I spent some time listening to flac via Duet -> EE Minimax dac and swapped the diy pc and TWL 12+ and again, no contest. Blacker background, less glare more analog sound, detail to die for.

I don't know what Pete does with these PCs, I spent time last night googling Litzendraught braided construction, and though I get the theory, it seems the payback is more than what I'd expect. Maybe it's the cryo he now does as well. I thought all this was magic 'pixie dust' meant to snooker the unwitting out of their cash, but not after this weekend.
 

Gene,

My VT-200 does not have an IEC socket on it and to install one is a biog pain (you need to remove both of the output transformers - ugh) so I have the 7+ put onto the end of the captive cord using an IEC to three prong adapter. I am sure that this is not as good as using the TWL cord directly into the amp, but it still yeilds some significant improvements. You should definitely give it a try.

Think you're right Charles, nothing at hardware.

AA gets about $20 a piece for them. I found the same thing on amazon for a little over 3 bucks each.  :roll:

One final test before I send the Seven Plus on to next lucky soul, bought an IEC to 3 prong adaptor, ran the Twelve Plus into the Quintet, and used adaptor to hang the Seven Plus off of the 4B captive cord, can't say that much of a change.

'Maybe' bass a little tighter

'Maybe' background a little blacker.

Or maybe not.

If I was going to keep the 4B I'd have an IEC installed, but I see myself going to something else for an amp, so I'll leave things 'as is' in that department for now.

And yet on my VT-200 the change was quite noticeable.

You know what Tom, it was a quick test of Aja after booting up system cold.

Made my post.

Now, after an hour of playing, surfing the web while Kamakiriad plays, sans 7+, re-cued the CD and added the 7+, back to surfing.

After awhile I realized I was tapping my foot along with the bass line, and here's the thing, the ankle of that foot is swollen like a grapefruit, so I don't want to move foot at all!

Still not something I'd call 'significant improvements', but the PRAT elements are better, soundstage a little better defined, and the bass is so nice, it's got my bad foot going.

Still, the 7+ is trying to push electrons through a 30 year old, 16ga. curly-cue captive cable, only so much it can improve.

But if I was keeping the 4B, I would definately have Pete make me a cable unfinished at the amp end and replace the existing cable.
