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.

Tube or solid state? What is the input impedance of the Spectral DMA? Consider the input impedance of the Spectral and the output impedance of the preamp, especially a tubed one. Not much concern with solid state preamps.
