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.
