Thanks Greg. I am considering the PS thing and this helps. I actually have a pretty quiet, very black background, great resolution and clarity, and great dynamics now with a complex of a audio brickwall surge/filter, a bunch of alan maher's little boxes and a Kemp Schumann Resonator, so I don't quite know why I am looking. But yours and Lon's praise of the PS rig got me going and you know........


Gopher,

Sounds like the less intrusive bass traps work. I made a bunch built into a naturally hidden alcove using rigid fiberboard. One diaphragmatic for low bass, and several others different thicknesses and covered with cloth for higher bass and low mids.

I wonder what those purple burning VRegs are. I had thought your setup was all stock other than the Treasures, but stock RCA OA3s burn orange, and this could help explain some of your missing warmth and romance. Are the VRs you have marked? May be OB3s, OC3s, or OD3s. Or they might have the voltage marked on them like VR90 for OB3s. I am thinking purple might be a OC3 or OD3....the lowest key options.

I suspect the OA3 might really help toward your more romantic/engaging goal. They will push your tubes with more dynamics, body, weight and more everything else basically. I think you are in for a pretty different amp once you have all your choices in place.

The gentleman I bought it from didn't roll tubes and gave it to me as he picked it up (locally) from Steve.  He did not have as many tubes as it sounded like the Torii normally came with.

I have VR150 tubes it appears, so when I get the OA3s in there I should be at least starting from a stock base.  I also couldn't tell what my inputs were 6N1P, 6922, etc.  When I turn my amp off later I'll try and read it again but I was unsure.

Right now we're working with:

Shuguang Black Treasure/Winged "C"s output
RCA 5u4gs/ Chinese 5u4g
VR150s/ soon to be OA3s
wildcard 6922 variant/Nationals

My amp is configured for 8 ohm/16 ohm, I do have a bass control, but it was added after the original sale by Steve and I do NOT seem to have the bias switch--it seems I have dual mono input selectors.

DAMN!  I wish I'd realized the Reg was probably a culprit--it was a suspicion, though not a strong one--had I known I'd have paid more and bought it locally...  Now I've gotta wait for these suckers to come from friggin' Lithuania  ;D

VR-150 is an OD3. I would say that your sound will have notably more density, dynamics, body, weight and texture with the OA3s. The OD3 creates the lowest grid voltage. Big difference coming your way! Maybe too much, but you will have to see.

I got an OA3 from tubeworld after I broke one of mine and it was not expensive if you want to get it done.

My 6N1Ps from Decware have had a diamond on them on one side and letters on the other.

If you have the bias switch, which I thought they all had, it is the one on the front right, right of the volume, the left of the volume one should be your input selector. Toward you should punch things up a bit and back more neutral.

The switches outside the power switches (on the back) are the impedance adjusting switches and create a big shift in the sound. Steve told me neither way is necessarily right or wrong....a taste thing.

Have fun!

Gopher, don't know, but I get the urge for the amp to sound like you want it to. It could be worth it to pick up a pair of OB3s too if you get some OA3s from a more local source. This would be a cheap insurance policy just in case the OA3 is too intense/dense for you. If the OD3 has you almost there, it is a pretty big jump from a OD3 to the OA3. At least to me it is.

Very interesting.

Density, body, weight and texture are already strong suits for this amplifier--I have a hard time conceptualizing more, but am excited to experience it.

I'm somewhat of a texture/density junkie, so it will be interesting to experiment.

This is just an observation, as I do not know the details electronically. But I think that with the big VRs, the general signature remains relatively similar with the different lettered/voltages of A,B,C,D.

In you case, as you change them, since your start is the lowest key one....as the grid voltage increases, the sound of the tubes downstream of the VRs becomes more.....sort of across the spectrum, but particularly notable is weight, body and bass. I think this is why Steve talks about using them to tune the bass in particular.

In my case, with various editions of my room/system, I used VRs to tone down the VRs from the stock OA3 to OB3 or OC3W, resulting in a slightly lower key presentation overall, less weight/bass, and a resulting sense of more midrange openness.

Lately I use either the OB3 or OA3, and for me when I don't want to use the OA3s, it is because, in that set, they tend to be a little in my face....good stuff but a little pushy. My system/room/tastes though. I'll be interested to hear yours.

I am almost afraid to take my new Torii out of its plastic wrap. I know that, once I do, my own tube rolling insanity will commence. My 1950s NOS RCA 5U4G rectifiers showed up today, too, so I am set there (with NOS Svetlanas as backups on the way), and I have a number of VR tubes as alternatives. Inputs for the Toriis are the Ediswans, and the outputs are the Treasures. but I am still planning to break in those V-caps using the stock tubes.

My ERRs are all but done, so they will be here soon. My Ultra has been in QC testing for some time now, but I expect it to ship soon as well. The net of all this is that they will all be breaking in together, I guess.

FWIW, and it's worth a lot to me, the woodworking and craftsmanship on the Ttorii are just beautiful. Built like a tank. And gets a lot of "wow" from everyone who sees it. Grin

Duuddddeee!!!!! You are in for some fun. You are also reintroducing speakers and room! Incredible. I wish I could be a fly on your wall! Congratulations.

I have been really impressed how smart and decisive your progression has been. No messing around, getting the stuff that is most likely to suit your tastes and setting. The ERRs are supposed to really work with less-than-perfect rooms = Smart....the Treasures have happy reviews from good ears and Steve offers them = smart....and so on and so on. I am really excited for you.

Thanks for the good words Will. I hope it's smart. Wink I look at it as a big case of "doubling down." I heard the Taboo, compared it to my previous/reference rig, and having read the forums and Steve's papers, and the few reviews I could find, I concluded this stuff suited me. I made the decision to buy what would—if it delivered as well as the Taboo—make me very happy without leaving me with a case of upgrade-itis. While not cheap, in today's dollars, it's much less expensive than I have spent on the upgrade merry-go-round in the past.

True, I have way more tubes than I need, but if I feel the need to upgrade, I have plenty of tubes to roll. And by going ahead and getting the power cords, ICs, and speaker wire I need, I figure I can sit back, break it all in, and enjoy the music and home theater.

Bob has been kind enough to share in words and photos the builds of my ERRs. Absolutely fascinating. And to all of you who have been generous with your experience and your expertise, thank you.

Pale,

Congratulations on the new addition(s). Be patient with the V-Caps.

FWIW the RCA NOS 5U4G's (ST) are my "go to" rectifiers (big, juicy bass). I've had the Svet's for a while, but can't bring myself to try them...

And just for thoroughness—and in honor of Lon—I picked up a few straight tube 5U4GB pieces.

If they had a definition Tube-o-phile in the dictionary, I’m sure there would be a picture of PR. Cool

Please put the stock tubes in and give us your initial impressions.....

Thank Goodness you have a Torii at last! With the V-Caps you're reportedly in for a long haul before you're "broken in" but i suspect you'll have quite a bit of fun along the way. Smiley

I know you'll be keeping us updated, and I'm looking forward to your impressions.

Lon, I think I am going to set up my first Torii with the stock tubes at the office, running off my headphone rig. I have a couple of spare Orbs that I can use for a speaker load. I can then schedule the Mac mini to play music for 5 hours at a time, take a break for 5 hours, and then resume. Over and over again. That way, I can accumulate several hundred hours before my Radials even arrive. This will help get the V-caps "out of the way."
