Tube amp recommendations to drive Joseph Audio speakers

I’m using Lab12 Integre4 MKII. In the process of auditioning it, I also auditioned Lab12 Suara and Lab12 Pre1. They sounded largely identical to my ears. You can consider the Suara, although if I am you I would consider selling your ARC pre and getting the more expensive integrated Integre 4 MKII instead simply because it runs cooler and the biasing procedure is painless (took me less than 5 mins to bias 4 KT170 tubes with the built in LED screen). Lab12 stuff really deserves to be more well-known, their tube amps compare favorably with the best SS class A amps out there. They are some of the best amps money could buy.

The Quicksilver amps used tubes penthode, the tonality ad clarity are not as good than tubes 300b or 2a3 but the power and dynamic are better.                              The Joseph audio speakers are not very sensible so it's a better choice to choose penthode amps.
 

Anyone have a pocket translator for this?

I would recommend a used Audio Research Reference 75SE. It’s 

Qualiton/Audio Hungary make a great 100 watt power amp for $5,5K. I own it and have been impressed with it. I pair it with an LTA microzotl preamp. Really happy with the combo.
