Any high end preamps out there where tubes off while HT in use?


Seen many lower end preamps that leave tubes off while in ht bypass mode. Anybody aware of higher end preamps like arc Ref 6se (which sadly leave tubes on) where tubes are off while watching tv or movie?

Not sure, but I think Rogue, Backert, and maybe VAC might have that feature.

Cary seems like a nice pre and only about $3k. Been around for awhile and not chronically upgraded.  Not sure what to make of price being so cheap?  Does it stack up well to arc or other high ends?
