I've a pair of Acoustic Portrait bookshelves with Scanspeak drivers. Sensitivity: 89dB at 8 Ohms. Currently, I've been driving these with Lyrita GM70 power amplifier. Being a 20W amp, this doesn't seem to drive the speakers that well. Especially, the lower frequencies are damp and imprecise. There is boom right now, which is primarily due to the room configuration (Earlier they were really great. I've changed the cables inside the speakers and that seems to have opened up the dynamic range).
I'm looking to pair this with a SS power amplifier to improve the microdynamics and speed. I like to retain the warmth of a tube sound. Therefore, my preamp (Lyrita Lync Pre) will remain.
I'd like to know these:
Additional information: This is primarily for music. Source is a network audio player that can handle hires (DSD, FLAC) files. I prefer music that is slow, soothing, ambient, meditative, open soundscape; good vocals). I'm a low-volume listener. Occasionally, I can crank up the volume and listen to fast music that needs a lot of dynamics).
Please feel free to add any other things that I should consider. Thanks in advance.

I'd like to know these:
- What is the minimum power wattage should I look for in the power amp?
- Is it correct that adding a power amp helps in achieving the goal that I've mentioned?
- Any specific power amplifiers that I should look for? (under 50k).
