Congratulations. I will be interested in hearing your impressions… after the 1,000 hours mark.
I auditioned in home, a brand new ARC REF160s… then bought one… breaking it in… then because of a weak meter, I got another new one… which I broke in. I was really surprised that sound really continued to improve through 1,000 hours… although most was by 600. Then my dealer lent me a borrow a pair of REF 160m mono-blocks for the last couple months. It has been fun. Same power and design.. exactly… but separated in two chassis. I run them in triode mode (70wpc)… the power difference makes a tiny difference. But the sound is a bit more natural in triode mode. After lots of time. The soundstage is wider and deeper with the mono blocks. My conclusion is that if I had a choice of what to buy right now… I would pay the extra $12K for the mono blocks… but would not now pay to upgrade (perhaps because of the house remodel last year). I will wait for maybe the Ref 160SE (mono blocks)… or the next higher redesign… ? Ref320?.
