If you want to inject some real warmth and feeling, try a tube pre amp. Sometimes having the right tube pre amp with a solid state amp can really bring awesome results! Proper matching of impedence should be no problem, with the right unit. I know matching components is nice, and will probably work very well indeed. But you only live once!!! ..I think...lol
Don Sachs customizes the Tubes4HiFi SP14 preamp.
The SP14 uses 6SN7 tubes. Cost depends on which options and tubes you chose; the base configuration starts at $1,699.
Upgrading the output caps to Duelund CAST PIO-Cu will set you back $375.
Upgrading one pair of the 6sn7 tubes to Shuguang Black Treasure CV181z will cost $129.
Changing one set of RCA inputs to XLR is $275.
Worth adding to your list of possible candidates. The only problem is that since each one is custom built by Don, you can’t audition it before you buy (unless you know someone who owns one).
I own one and can attest that Don is a great guy and very easy to work with. He will work with you to ensure that the output impedance of the preamp matches the input impedance of your amp.
And yes, his preamp is an incredible performer!
analogluvr: Tks for your opinion. One of my friend also suggests me to choose a good solid state Pre. from famous brand for the longer life than the tube one. What I care is once the vintage has problem, whether I can get it repair and recover.......... (according to the opinion of one audio service engineer, some times, too old gear might hard to find parts which had been produced long time 20~30 years ago.

I thought you were interested in vintage gear since you mentioned that the SS preamps you were interested in were up to 24 years old. With that said... try to audition a Primaluna Dialogue Premium preamp. I own one, and it rocks! Lots of info on line.
Thank you very much for your response. A good tube amplifier esp. the vintage need a specilist to exam but I am not an electronic expert. And the new one are quite expensive. Also, it is important to match the pre-and the power amplifier together to push the speaker. There is very few dealer can provide such kind of service...... In addition, as a vintage gear, some are difficult to repair or finding the parts. ...... Many of the audio brands have been gone..........
