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.
Tube amp recommendations to drive Joseph Audio speakers
Looking for a tube amplifier to drive my Joseph Audio Pulsar 2 Graphene speakers. Preamp in the system is an Audio Research Reference 2 Mk II, cables are full loom Zavfino.
Have been using a Pass XA25, but while detailed and clean, the sound is just a little too yin (lean) for my taste. Want a little more tonal color, density, and bloom to the sound.
Hope to stay around $5K new or used.
Thanks!
