To make it lighter?
b-square said:Reducing the weight of the amp makes the sound lighter, just as relieving tension in the cables by removing the zip ties makes the sound more relaxed.

I assume that your speakers might have nominal 8ohm and SPL of 86dB/m/w. If so,
100dB/m/32W . . .
What is your normal listening SPL in your room with your lovely boy?
mert said:my speakers 4 ohm, 86-88 db, but may drop to 3.2 ohm. It seems around -45db, amp will switch to Class AB. However, recording quality of the Sacd/CD may vary: with some cd, you may make a critical listening -45db, amp will be still in Class A mode. With some cd's speaker require more power, matterfact , you make listening in Class AB mode.

This is probably not what you want to hear but if i were you i'd get rid of the pretty cupboard and buy a high performance rack, something with carbon/kevlar shelves and properly designed vibration dissipation. I'd bet anything the improvement will exceed many times a simple cap upgrade.

but, i can't imagine that those speakers are performing at their best placed like that.
I would say spend the money on getting a new room.
Let those puppies breathe! (or Sophia's)
"The Pass Laboratories™ X250.5 is optimized for loads nominally rated at 4 ohms and above. You can run the amplifiers into a lower nominal impedance without difficulty, and we are not aware of a speaker on the market that presents unusual difficulty with these amplifiers."
The amp seems to have enough Class A bias current down to nominal impedance of 4 ohms. Nevertheless, if you are not satisfied fully, I would consider increasing Class A bias current and decreasing the rail voltages (considering the same heatsink temp) rather than any other mod. I believe that Papa would suggest how to do through e-mail if you kindly send him your question.
Now it is turn for internal modifications!
