New preamplifier - Backert Rhumba Extreme, Aesthetix Calypso Signature, Ayre KX5 Twenty

if I recall correctly if you make any volume adjustments while watching a “movie”  the entire system does not stay “in sync”.

@dotto81 IIRC the volume of the home theater processor is controlled by a remote. It feeds that signal to the preamp. If you have a home theater bypass, that is simply a preset volume setting which is usually unity gain in the preamp, thus allowing the remote to have full control. So that's no different if you were to simply use a known volume control setting on the preamp- its literally the same thing. 

Based on your personal listening preferences or style of music you like or listen to most frequently, you may choose to go with a sonic signature that provides the sound you prefer. 

Hopefully the preamp isn't coloring the sound! But the things that make a preamp good for rock will also make it good for classical or jazz, since the same bandwidth is required. Quite literally there's never been an electronic device ever built that favors one music genre over another!

I sent an email to LTA asking for recommendations for a work around to the HT bypass shortcoming.

@dotto81 The solution is very simple. Find out what volume control setting satisfies the home theater setup. Use that setting when using the home theater processor as an input to the preamp.

I listen to a wide variety of music from Jazz to Blues. Classical has been finding its way more into my rotation. 

@dotto81 Your taste in music really should have no bearing on the choice of preamp! The electronics do not care what the genre is; its job is to amplify the signal with the least coloration possible. To date no-one has ever been able to sort out how to make electronics (or loudspeakers) that favor a certain genre.
