Yes, Audio Research Ref75se. I have been listening to mine (with an ARC Ref6 Preamp) for quite some time and with the right dac, speakers & cables, its been a couple years now that I have trouble listening to my system because the music keeps quickly distracting me - and sometimes keeps me up too late at night. This system does require good source material though. More than enough bass to satisfy me and for me my exactly the right balance of resolving technical detail and musicality.
Tube amps under $7500
Ready to experiment with combinations never before (or not recently) tried. Step one requires a tube amp. Now looking at Prima Luna EVO 400 which sells for 5K. Any other tube amps I should consider in this price/feature range? Must come in silver with balanced input. For pairing experimentally with various tube and SS preamps. Efficient 4 ohm Legacy speakers (and the room/setup) are the constants.
