Michael, I think it was the bass adjustment control set at a spot that was not advantageous with your speakers.  As mentioned, it does not operate like a typical tone control that boosts or cuts the bass, rather it acts as some sort of damping control, from loose to tight, with the 'correct' setting dependant on the particular speaker it's hooked up to and how it sounds in your room to your ears.

How are the Super V's coming along?

I'd love to eavesdrop on that conversation.  Maybe Steve will chip in on the thread so we can all benefit.  

I suspect that the particular speaker's mechanical compliance is a big factor on what the ideal bass control setting would be.  Also, if there are any passive crossover bits in there would have an effect.  I would expect something like a FRX2 or Hoyt Bedford full ranger to benefit from a different setting than, say your proposed P-Audio via passive network.  I would expect your Tylers (those look kick ass by the way...bet they sound awesome with the Torii...green with envy over here) to interact differently that the speakers the previous owner of the Torii was using, unless he had the Tylers too.  Could be that passive network bits disrupt damping, and so the full-left/off/whatever-it-is works best with the Tylers.

Seems to me that Steve has come up with something far more useful than a simple tone control, giving great flexibility and adaptability to a wide variety of speakers.  If it is indeed some sort of 'dial-a-Q', then every speaker would benefit from a spot somewhere on the Torii's range of adjustment based on it's underlying characteristics, unique to each different speaker.  I know of no other amps that have such a thing.  That's just flat out pretty cool, isn't it?      

Unless it is the bass knob adjustment in concert with bad impedance matching between the amp and speakers, this would surprise me. The amp was designed using a wide range of speakers with the objective of the bass knob being an adjustment for sound taste preferences and room difficulties as opposed to driving a speaker too hard or not. But it is conceivable! I look forward to your findings.

Following my latest thread "Wow, what happened", I think I found the problem. A failing and finally failed transformer. The Torii is on it's way back to Steve for a rebuild.

It's very quiet around here...

The mystery solved! I'm sure Steve will set you right.

BTW, I thought it might have been my setting in my Dac,clock, Audirvanna, mac settings, just put back my Sim Moon W-5 back in, sounds brand new. Could it be the Decware??? I've done countless combo's on the Torii.

Hi Lon, Thanks for your interest.  Both channels are affected, 6N1p-EV (not 2P) are in the correct sockets. On the tube it reads 6H17-EB, the box its from reads 6N1p-EV. When I read MichaelHiFi from one year ago when he states "bass is a mess", I think these would be my words exactly. Everything, midrange, very dark sounding, Treble all the way clockwise from the get go, no issues there but not the air of the SS amp, no hum, dead silent. I know the V-caps have a ways to go. Turning bass control full clockwise, more cone movement (using filtered pink noise 400 hz and down)but does not change the overall character of the issues. My audiocontrol RTA shows a at least a 3 db spike over the SS amp at 50-60 hz.  My ignorant conclusions, 1. Am I clipping the amp? Can't get much over 90 db (largish  room 16x27x12, sit 10 feet from speaker), without becoming unlistenable, 2. 2 bad tubes?, or 2 wrong tubes, 3. transformer. 4. Lastly, this is the character of the amp and its a mismatch for the GV's, maybe due to the fact it was voiced on very efficient speakers that sometimes are in need of bass. Could power going to the bass be sucking the life out of the amp allowing it to clip.?These GV's are EZ speakers to drive. BTW, 4 ohm setting, everything collapses relative to the 8 setting. What does a failing transformer sound like?
