In Reply to: RE: You use two preamps at once, yet you worry about stuff like this... posted by Ozzy on May 16, 2012 at 08:39:05
The results are all I care about. If I worried about dickheads like you, I would not have them set up the way I do.
As it is, i am NOT worried about dickheads like you, so I use a tubed preamp just for it tubyness factor into my main preamp. Not YOUR problem.
Oh sorry in your opinion it is your problem. You must stay up nights worrying about it.

I'm actually quite interested in this use of dual pre-amps - can you provide a link to further discussion of this, or give a brief explanation of how it is implemented?
I would be interested in using the phono stage of my Wrightsound WLA20 into the NAD326BEE - so far, I've tried it directly into the amp stage, but also using the tape out/in connections.
Piping a phono stage into a line level preamp is no different than had the phono board been in the line stage. The very best separates operate that way.
What Liz does is daisy-chain multiple line stages and throw away most of the unnecessary gain. As for me, I go in the diametric opposite direction - I eliminate redundant gain stages where possible. My digital sources drive the power amps directly. A (single) preamp is used only when the equalization and gain is required by a phono source.
Originally I bought a set of Brystons... preamp BP-26 and amp B4B-SST2 to replace my old Adcom preamp and Forte'4a amp.
I had too much gain on my digital with the Brystons so I wondered what I could do to attenuate the output. I still had my Adcom, so I stuck it over at the amp end of the 7 meter preamp to ammp wires to see if attenuating the signal there would be 'OK" (this is where Ozzy decided to start in on the two preamps shit BTW) anyway I was not fully pleased with the setup, and still wanted a buffer for the digital anyway.I had a problem with my digital stuff and wanted to try a tube buffer.
So I bought a cheap ($150) tube buffer, but it did not do much for me.
I happened to see a great deal on a VAC Standard preamp on the gon, (($1,500 for an upgraded VAC Standard ($4,000 plus a grand for the factory mods)) so i jumped on it.
The VAC does exactly what i want to the digital signal as a glorified tube buffer, plus I can now leave my main preamp volume at a good position (unity gain) and for digital, use the VAC volume control.
Wonderful.I also have another preamp laying around I want to keep. An Audio Research SP-15 two chassis preamp with a great three tube phono section.
So have that going to my Bryston preamp also, and just use it sometimes, to just keep it in good shape (better than in a closet)Anyway the output of any amp into another is no problem electrically.
Soundwise as Ozzy states, it may be idiotic if it degrades the sound. However for my needs what i now use and how i use them works out just fine for me.
The Adcom when it was in the chain certainly did degrade the sound.
The VAC is perfect at want I want from it, and really my digital is exquisite at this time with no interest on my part to change any of it soon.----
You can use the regular output, or the tape out if you want to avoid the volume control.
For the Vac, having the Bryston at unity gain, and using the VAC to fine tune volume works best.
For the Audio Research Sp-15, using the gain set at -24db, and volume at maximum, using the bryston volume to fine tune the volumeworks best for that pair.And for Ozzy, i guess his repeated 'rubbing it in' crap is just his way of reminding me he thinks of me all the time, I guess some call that love.

Thank you very much, Elizabeth, for your very complete answer, and thanks to E-Stat for your helpful comment.
This may provide a way to use the excellent tube phono stage of the WrightSound, while still retaining some of the benefits of the NAD's preamp section.
Dickhead? Are the gloves coming off? I don't remember ever calling you a name...
If you ever hear the "right" preamp in your system, you will realize you only need ONE.
I just think it's funny to call you out and see you spin like a top.
Good job!
Don't worry about avoiding temptation. As you grow older, it will avoid you.
