I would consider the Coincident 300B Power amplifier monos...single ended for efficient speakers, but with plenty of bass foundation, liquid mids and extended, soft highs. Israel is a good guy that has been in audio for decades! P
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.
