Is there any reason that you would get an ARC preamp- there are other balanced line tube preamps out there. The Ref series are some of their better sounding preamps though.
arc reference 300's preamp ideas
I recently bought some audio research reference 300 mono blocks and currently have a single ended preamp. Currently Cary SLM-200 mono blocks, thinking about selling them btw, with a mystere ca21 preamp. Awesome sounding combo but time for something new. Need to know best preamp with BALNCED outputs to go with the reference 300’s. My top end is 6k.
