I have tried reading the descriptions on all the different pre-amps Frank offers but am a little lost as to what is best for me. I am most likely going to be pairing the pre with his SET 120.
I already have a dac, so digital is covered. I will be buying a record player but that is a long ways off. So just looking for a good pre to plug my dac and cd player into. I am also using a pair of ZU Audio Omen Dirty Weekend speakers. One of my question is this, do the tube pre-amps have to be adjusted? Or are they plug and play and don't worry about it? I really don't want to have to worry about changing out tubes or biasing them or anything like that. I want simplicity but also extremely good sound quality, hints why I am on AVA forum in the first place.  :D

We have two excellent very low cost choices for you.

Our Vision RB solid state preamplifier, $895.  This is a very clear and transparent discrete transistor solid-state unit with no rough edges or user fatigue.

or

Our Transcendence 10 RB vacuum tube preamplfiier.  This is our simple but sophisticated basic tube preamp that like all AVA vacuum tube preamplifiers, has multiple regulated power supplies - - -  a separate regulated power supply for each plate of each tube.  This allows the tubes to do exactly what we want them to do.  The unit uses 6922/6DJ8 tubes for each channel.  There are no adjustments when replacing tubes ($35 a pair) after several years of use.  Musically this is a very engaging and transparent preamp.

Why do we build both great tube and solid state equipment?  Well, some people would never consider a solid state unit, others never would consider a tube unit.  We get the best out of both technologies because we can and thus serve everyone better.

Either is a great choice with the SET 120 amp.  We have the combination of the SET 120 paired with a T10 RB out for review in The Absolute Sound right now.  You will probably hear more about that soon.

One other consideration would be to consider what the main issue with your system has now.  If it is a bit too bright and hard, then choose the T10.  If all is really neutral, then the Vision RB will bring the best resolution out of the system.  They both are hard to tell apart when running in our reference system.

Note that our RB (real basic) chassis is common to both the T10 and Vision, this keeps the signal path as direct as possible and your cost at rock bottom.  Four sets of inputs, two sets of outputs, great headphone amplifier, and very quiet operation.  Vision Q phono section and remote control volume options available for both.

Thank you for the response. The T10 looks like the way to go for me. I am pretty excited. My next question is, the dual outputs, are those treated like sub out? I have dual subs so would I plug in an rca out of one and and rca out for the other?

The preamp has two pairs of left and right audio outputs.

Use one pair to drive your main stereo amplifier, the second pair to drive one or more subwoofer plate amp.

No issue changing tubes, they are plug and play at $35 a pair if they get noisy years down the line.

So no biasing is needed? Just forget about it for years?
That is what I am looking for. I don't want to have to think too much. I know there are a lot of guys out there that love rolling tubes to get a different sound, I am not one of them. I just want it to sound GREAT out of the box and sit back and enjoy the music!  :D

Frank usually mentions that all tubes in any AVA tube or hybrid products are run gently and well within their design limits, so they maximize the lifespan of the tubes. He didn't bring that up here, so I figured I'd save him the trouble.

No biasing needed for the tube preamps.  Nothing  to worry about.

Sounds like a real winner. I am pretty sure I am decided on the pre, now I just have to come to a decision about the amp. Either his SET120 or a couple of different options with some low powered Class A SET amps. Choices in this hobby are tough!

From everything I am reading, your SET120 seems to be the kind of amp I am looking for. Plus I wil have plenty of headroom if I want to get crazy, which I do from time to time while playing some Nine Inch Nails or Primus.  :D

I am looking for fast! Attack and decay, well controlled tight accurate bass. Transparency. Floating 3d holographic soundstage. The snap of a snare drum or crash of the cymbal. Also love the hard punch of a kick drum. But then play a woman's voice with delicacy and magic. I want an all in one GREAT amp! Like I have told others, I am building one of my forever systems right now and it's being built around my upgraded version of the ZU Audio Omen Dirty Weekends.
