For my part, I’ve owned a VT 100 mk II, a SP 10, a LS 16, a phono 5, ... i like my ARC stuff but must admit I find, and general consensus is, they definitely have a somewhat ‘buttoned down’ house sound. Like they’re afraid of being accused of sounding tubey or something.
For me, I like it because it puts the music on display rather than showing off artifacts introduced by the component manufacturer. At the same time, it certainly shows off changes in components up and down the line.
Sometimes I wish I had more snap and thump. Sometimes I wish they were a bit more forward. But for what I listen to, I think they do a pretty good job.
That does not keep me from getting that ‘itch’ to try something new every now and again.
I’d love to have the chance to own, or even have some extended listening time with, a reference 10,…but right now, I think I’ll concentrate more on paying off the house ...
