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?

I use my Bryston amp for HT pass through. RCA to my Luxman tube preamp and balanced to my Krell Showcase surround processor. Just flip the switch on the amp.

Do many amps offer an input selector?  Even better if done with a remote. Makes all the upstream ht bypass issues a lot easier to deal with, ie by not having a need to do anything.

my guess is the connector complexity may no be good for SQ.

I think ht connect to stereo is an issue that’s overdone. It can be done quite well.

why sooo afraid?
