Dreaming of a DIY 8W Class A amp designed by Nelson Pass?

Even without break-in they improve on the stock Meanwell SMPS. Increased dynamics. Weighty and extended LF.

I have found that going from switching power supply to a linear with a very large capacitor bank will yield significant improvements in bass strength and body.  Along with all the other improvements! lol

Pass ACA measurements and review.

Wow...what an awful review.

Like I stated earlier, within it's power limitations and matched with the right speaker(s), this is a wonderful sounding amplifier.

The guy who runs ASR is like Julian Hirsch.  He has no ear whatsoever, and biases his reviews after he has seen the measurements.

lak,

I would not get too hung up on "upgrades" and start with a basic kit and just getting it to work, enjoy the sound, and learn as you will probably make mistakes.

It is hard when you don’t have experience, as what appears as "experienced upgrades" are often just stuff thrown against the wall with hopes it sticks ..... and usually claiming that it does.

There are DIY forums more appropriate to a beginner and people generally more experienced with electronics who can walk you through it if you go that route.

I tend to get confused when people with experience begin talking about upgrades that will increase the level of the builds. I’m in favor of the upgrades but my inexperience makes the upgrades look confusing because I no longer have the step by step directions to follow with the exact parts I need.
