Looks very interesting! Lots of good reviews on it. Thanks for sharing. Are you going to try building this?
I have built the B1, BA-3FE, and Korg B1 preamps so far. They are all great designs and very useful in different applications/combinations. As stated earlier...it’s a mood thing.

That’s great information! Thanks! I’m trying to decide the scale of my next project ...I’m leaning towards full blown monoblocks.

I does have an advantage...it can be ordered as a full kit which gives individuals with less experience a better chance of completing it.
Another option, rather than building bigger and bigger classA amps, is to split the signal actively and bi-amp the speakers. Place big watts classAB on woofers and classA on rest.
To be honest, i will eventually build Alpha Nirvana, i got all the parts. Just need to finish bunch of projects first. It will be forced air cooled.

Adason,
I agree that good Class AB or even Class D is good for subwoofer and woofers. Mid bass, mid, tweeter benefit from Class A. I have done an active setup with Class AB on woofer and Class A on tweeter and that sounded very good.
I didn’t know you got the Alpha Nirvana parts already. Vunce just finished up his and it looks great in a 5Ux400mm case. Runs at 47C so still plenty of room to go thermally.

I came here to say exactly that!
And look, Papa already has everything waiting for you:
Analog Crossover Network – diyAudio Store
I would have to modify my conventional speakers to make that work. So the question becomes...do I dare to modify my commercial speakers? Probably, but what would that do to their resale value? I know some would have me getting into the DIY speaker building side of things, but I barely keep up with my electronics projects.
The lowest hanging fruit is to go active xo on only the bass, while leaving the top end passive xo.
That sounds like a cool idea...now it's finding a place to start. I'll do some research. There has to be someone who has done this with a commercial/conventional speaker. Any ideas where to start looking? I just wish I had speaker more "moderately priced" to start tearing apart.

Hi KevinHeem,
If your into another diya project, I have a pair of fully operational Model 6 amplifier boards removed from their heatsinks. I believe the only difference between the model 4/6 is the transformer voltage and bias current.
Model 4 used lower voltage but higher bias for Class A. You could make your own customized Model 4.5 😀 (Model 6 is 200wpc 😱)
Cheers,

I need to put my M2X back together first. It's getting a new SLB power supply😉 thanks for the offer.
If I hadn't borrowed this Model 4 from my friend I would have no music in the house...that would be baaaaaad!
No music... that would be baaaad!! You need multiple amps 😀
Hopefully you can get your SLB/M2X back online quickly.
