PS Audio BHK Signature Preamplifier or Audio Research SP-9 Mk. III?


I’m currently considering trading in my (circa. 1993) Audio Research SP-9 Mk. III for a new PS Audio BHK Signature preamplifier. Any thoughts? Would it be an upgrade, lateral or just different? Should I just hold onto the SP-9 and upgrade the caps, etc.? Thanks in advance.

If you use phono on the SP9, you’ll need a separate phono amp with the BHK. I believe PS Audio do a trial so you can try it out. There are a few for sale on US audiomart for about $3500 if you want to buy used.
