Analogue only preamp ideas? - no need for internal DAC!

The McIntosh C70 is awesome but doesn’t offer home theater pass through.  Same issue with the C22.  
If you want HT Passthrough with a tube stage, check out the AVM PA 5.2.  It is in the same price range as the C22 at $5495.  They offer a phono card that you can add for $600 if you wanted a phono stage added to it.  This can be done at a later date.  German made, AVM offer superb build quality and incredible sound.  
Rogue is also a fine choice and I know they offer pass through.  The RP7 or RP9 would do a wonderful job in your system.  The RP7 is $5K, I forget the price on the RP9.  
I am an AVM dealer.  I have no relationship with Rogue, just am a fan of the brand. 

I think tubes are better than a preamp with a dac.

dont understand why someone who has a great standalone dac would buy a preamp with a dac.  Spend more dollars toward a preamp without a dac and it seems tube device is just better.

concerned about tube maintenance and long warm up period, need to learn more

thanks. 

Tubes in a preamp take 20-30 minutes or so to warmup.  This is irrelevant for pass through.  You will find that until the tubes are warm, sound will be a little flat.  
AVM tubes should never need replacement and were explicitly designed for AVM.  There are no alternatives.  Expectation is a minimum 10K hours

Rogue or other brands use standard tubes that are rollable.  You should expect between 4K -10K hours out of standard tubes.  
You have to be a little cautious in pairing tube preamps with SS amps.  The AVM is adjustable and is designed to pair with SS or Class D gear.  The Rogues are well suited for pairing with SS.

i have a customer who is considering trading in an ARC SP20 which is a great preamp that will work with SS gear And would work well for you.  The SE 4 input is the home theater bypass.  I could help work out a sale between the two of you or buy and resell the device.  

you don’t need a preamp if your dac has a good sounding volume control. I had a very nice newer McIntosh preamp that I sold because I hook up my dac straight to the amp and I have no need for analog sources like a reel 2 reel or tt setup. Some dacs sound better going thru a preamp so you might want to audition a couple of preamps and compare that sound against your dac connected directly to the amp

Why not buy a phono amp and run it through a volume control direct into the power amp(s)?  Less components and less wire.
If you want to listen to vinyl only a pre-amp is not contributing.  Indeed it is just adding its own signature and a little more noise.
The money you save on pre-amp and wire can go on a better front end, or whatever.
