...I've noticed that this amp loves the percussion

This is the common reaction of everyone who have listened to it. The kicks and the crashes come alive!

new baby monster born !


*100pF swap to 220pF & 22pF swap to 33pF, use what i have in my drawer

Shaan, are those values critical?Can you use 33P?

 

[shaan]

Hello meanman.

The value is not critical. You can use 33pF with no problem.

If you feel good with the audio-grade capacitors then by all means get them.

I can't assure you whether the audio-grade caps are worth it or not but last couple of days I have been doing comparison between different 2200uF caps, namely Nippon-chemicon KZE(my default option), Panasonic FM and Elna RJG.

Result - No audible difference whatsoever between the three models.

I updated my Amp to use Nichicon FG 2200uF/6.3V in parallel with 0.22uF X2 caps and noticed a difference in all three sections (high, mids and bass). In my listening test it has became more transparent.

I've built the V3 with all panasonic cap. But no audible difference at all

Both statements are valid from subjective point of view. We all hear differently...
