I have a Parasound P5 which I use & is integrated into my home theater set up/ 2.1 stereo set up.
I have an Integra DRX-3 acting as the HDMI Processor - off loading the amplification to a Parasound A21+ for the fronts. And an Emotiva XPA-4 on the surrounds and center channel when I use it. The system specifics are in my signature.
I got the Parasound specifically to up my 2 channel listening experience. I wanted the home theater bypass to integrate the unit into what I already had built, which worked very well. I also very much wanted bass management and separate analog subwoofer outputs to add in the fun when I am actively bi-amping speakers or utilizing the sub(s) while listening to analog sources.
I also did what another member suggested, by building a balanced 2.0 channel system ; albeit combining the two systems into one since my living situation currently only allows for one room to be dedicated to such purposes. So I use an RME ADI 2 as my main DAC, balanced through the P5 for 2.0 or 2.1 channel listening. I also have my OPPO player plugged into the P5 via Coax, a tape deck on RCA, 2 turntables, and the loop back from a Tube amp when I want some "fuzz". And finally the Integra on bypass for all my HDMI and surround sound listening/watching experiences.
The P5 is basically maxed out on the connections but it's been a great unit for me. Very convenient and I do feel that it added a more realistic sound to my music listening sessions. Of course the DAC and source etc play a huge role, however I did note the sound being more spacious with a much easier time placing performers and hearing background nuances. I will also add that I got my pre-amp for a very fair price from the original owner who was consolidating from separates. So it pays to browse around a bit unless a warranty/guaranteed return window is an absolute must.
Lastly the only drawback I have experienced with my P5 is the Alps analog volume potentiometer. Low level channel imbalance can be annoying and If you don't use it much past a 11'oclock or so it becomes scratchy while manipulating the volume. Instead of manual cleaning, I've found if I play some music (PCM so the volume can be lowered digitally) - lower the volume in my music player to ~ -50dB, and open the volume pot all the way. Then close it and work it back and fourth, with voltage going across it. Usually this fixes my issue and It's only happened a couple of times.
Parasound made some changes on the P6. Going to an electronic volume control was a big plus to remove any low level channel imbalance, potential for dirty/scratchy pots, and biggest of all numbers to see your volume in the dark! Lol. I've had good experiences with their brand without having to pay an arm & a leg to get there. Hopefully something comes together for you!
