100W Ultimate Fidelity Amplifier

Did some listening to the amp with some full range speakers, Mark Audio Alpair 7 drivers which are only 4" so limited bass but their mid/tops are very revealing.

Overall impression was excellent dynamics/clarity. Top end very detailed without any harshness. Bottom end very clean tho I cant talk to the lower frequencies. Very pleased with the amp so far. I have been building/using "D" class amps in the last few years, the better ones have great dynamics but can get a bit aggressive. The AX14 seems to have the dynamics without so much aggression.

Next step will be integrating it into my active 3-way driving the BG Neo8s mid panel.
 
AX-20R

Apex AX-20R, tested and working good.

You can match them with your DMM, if it has the provision or with your 10USD aliexpress / ebay transistor tester.

apex designs are quite liberal when it comes to matching and use of components.

Thanks Prasi, probability of finding a couple of matched pairs from a set of 20 to 30 transistors is fair enough? As they are cheap INR 5 locally so with 20 its just INR 100 and if I can get the matched pairs then good enough :)
