Too much gain can be a double edged sword.My first Class D amp was the PS Audio HCA-2. The early models had 30dB gain and worked great with a passive preamp. On the other hand, the background hiss was audible with an active preamp especially with somewhat sensitive speakers. Without announcing it PS Audio lowered the gain on newer versions of the HCA-2 amp.
On the Cary side, some of my favorite electronics came from Dennis Had including the budget friendly AES/Six Pac EL34 tube monoblocks. I thought the SLP-05 preamp was probably the best tube preamp I ever owned and I really enjoyed the Cary CD 306/200 CD player. (The 306/200 had a somewhat 'hot' and robust output signal making it a great source component for a passive setup).

My current setup gives me "just enough" gain with my rather sensitive speakers. The amp is, of course, single-ended (RCA) with volume cranked up to 11 lol. The 8 WPC 300Bs and 6SL7 driver provide more-than-adequate gain in my small-ish LR.
Patrick McDonald, who was the engineer for the music (and has a part in the movie playing himself) for "This is Spinal Tap", taught me how to engineer a record.
I love that the "goes to 11" thing just won't die!
