...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... 🙁
