I didn't see in OP integrated vs amp or wattage requirements. FWIW, I've got my Raven Blackhawk integrated with NOS tubes I've settled on and it's way better than stock and expectations. No XLR. OK, I'll throw in for Don Sachs Valhalla integrated. 34 watts with the larger pre tubes like 6SN7 etc. Has XLR but I think you'll only get the (beautiful) wooden chassis. I've looked hard at Aric and Qualiton too for next amp.
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.
