Adding a preamp to HT setup


i Have been convinced that adding a good preamp with HT bypass to my system will improve my 2-channel listening experience. I have read multiple threads here, and reviews all over, and there is an overload of information.

the 2-channel system is Aerial 7T’s, Odyssey Stratos amp and Oppo UCD205 player (I still use discs), and I’ll feed streaming in to the Oppo from the Marantz pre-pro. No vinyl.

the room is 19x12x8, and ‘live’, hardwood floors with a rug, drywall all walls. The rear of the room is open to the kitchen.

the improvements I seek are in soundstage focus and solidity, along with depth. Greater resolution of detail (love the little things that come out of recordings that make it real), and air around performers. All the things that draw us into a performance and involve our emotions.

i have an interest in what tubes would bring to the party, but I have no interest in spending all my time swapping out tubes to tailor the sound, I just want to listen to and enjoy the music. 
HT bypass is a must, obviously, and I’m curious about the lifespan of tubes given that my ‘normal’ everyday use of the system includes tv/movies where the pre won’t really be involved, except to pass the signal. I don’t know if there is an option for a pre amp to pass the signal through when not turned on, but that would be my preference.

Music interests range from Dire Straights, Pink Floyd to The Tenors/Josh Groban, to instrumental guitar...vocals and instrumental realism are big for me.

im comfortable buying used to stretch dollars, and would like to keep it below $2K, but would double that if convinced it was worth it.

I would check out the Prima Luna Dialogue Premium. I had it w/my older Aerial 6's. was an excellent combo. Tubes are auto bias and they last a long time. Currently w/my HT setup I have a Luxman CL38U-SE. w/my Aerial 5T's. Best preamp I've ever owned. Doesn't have HT pass through but I hooked up my Bryston Amp w/balanced cables to my HT processor and the RCA outputs from the same amp to my Luxman. I just flip the switch on the amp for movies or music. Woks well. So you really can work around a HT passthrough giving you more choices.
I had my Prima Luna for 3-4 years and didn't have to change tubes. They build their products w/lower gain to preserve tube life. My current Luxman CL38U-SE is 2 years old and as quiet as the day I bought it. The only tube preamp I had a problem w/was a CJ ET-3 SE. Has about a 26 gain factor and just ate the 6922 tube very 6-8 months. Was like clock work and it got noisy. Like sitting on a time bomb. That was my personal experience.
Yes you use both outputs. The Bryston SST2 2.5 on the back of the amp. Switch up the balanced outputs are active. Switch down the RCA connections are active. I wrote to James Tanner about this and he said it's perfectly acceptable to use the 2 channel this way.

By the way give Klaus a call see if it's ok to hook up both the balanced and RCA. You can also try it if you borrow the Prima Luna.
