ampifier desing topology versus part and spec

[YUTK]

In Ampifier desing you think obout it when topology versus part and spec I try and try to compare it sometime I listen audio amplifier not good spec THD but i hear someting different it good sound

Hi YUTK,

I used to live in Lardprao when designing for Magnet.

I wish you luck in listening to different topologies for a characteristic sound. Most designers are fairly adept at taming the character of certain designs, particularly output stage configurations.
However, to my ear/brain the transparency of JFET inputs is clearly discernable. In a honed amplifier. Of course you need high transparency in your ancilliary equipment or the detail's all in the mire.

Hi, Amplifier guru

I'm clonning Jfet input differential of UGS 3'4 from Pass Labs.
If you're interest spec of them you can mail me to download schematic & pcb

If you like Jfet (more than tube) I can help you.
