Under $10k budget Preamp suggestion, please.


I'm upgrading my system and considering next preamp right now in this budget. If possible, I'd like to find ones having retail price around $5-8k. Here's my setup

Transport: Hiend music server using Digital balanced + Superclock as master
D/A: Esoteric D-05 slave to transport
Pre: Considering here.....
Power: Spectral DMA 180 (May change later)
Speaker: Rockport Ankaa

I'm considering Karan KA L at the moment since I couldn't think of better alternatives right now. I feel my system needs a bit more lower frequency for suitable tonal balance because D-05 has inferior bass comparing to Alpha DAC which almost fits in my system.

I used to consider Ayre for a change but when I tried K-5XE in my system, it lacks synergy for bass reproduction. However, reading all replies here giving me some thoughts for actual upgrade now. Thanks everyone.
The anti-passive nuts may come out of the woodwork but you have a great setup to try it on. A Placette or one of Jeffrey Jackson's transformer based units would work well. Unless you need the gain you are better off without the coloration of the active preamp. Cheap enough to try and why spend $5-8K when you can get better results much cheaper, that is unless you are one equates more money with better sound.

For solid state then I would have to recommend one of Stan Klyne's series 6 or 7 if you need balanced inputs and outputs.
Well the question here really is which pre-amp is best for your needs. As has been said many times before, if you're going to use a ss amp, then add some balance with a tube pre-amp (eg: Hovland HP100) or if you're running tube amps, add a ss pre-amp, however based on your need for more low frequency oomph, at your budget level take a look at Nelson Pass's statement pre-amp X0.2. That is a serious 3-chassis reference pre-amp. There is one for sale right now on AG for $4200 that can't be more than 18 months old. That is a $10k retail pre to be had at a bargain.
Melbguy1,
The newer XP series preamps from Pass are better than the older X series. I had the X-1 and the now the XP-20 and the later is much better, though more expensive. Pass believes that the XP-10, a one-box unit is sonically superior to their former reference three-box X0.2. For less than $4K, I would look for a used XP-10. But I'm not sure I would mix Pass with Spectral. Why not at least listen to the Spectral preamp?
