Hi - I can't see any BUTTON or FIELD where I enter a question in the ACA Forum and I can't find any explanation explaining how to post a question. I am typing this into 😛OST REPLY: or QUICK REPLY but I assume this field is to reply to post #8329. I have questions about the blue rear panel switch in the Build Guide. Thanks.

Hi Mooly - thanks for the response which is appreciated. I have now posted a question regarding how the blue switch on the rear panel of the Amp Camp Amp is orientated. The build instructions, so far as I can see, do not answer this question. Thanks Geoff
@melbourne - see step 32 and onward in the build guide. If that does not help, please clarify.

Alright, the M2/M2X looks promising, more power, less distorsion, DIY PSU etc. Are all the specs for the M2 valid for the clone M2X as well?

The higher noise spec for M2, is this something that might be significant in some applications and something a user might notice?
I would expect the M2x specs to be pretty much the same as that for the M2 since
the difference is the ability to use different front end buffers.
The higher noise may be an issue if you use very sensitive speakers. I didn't have
any problem with my 90dB speakers. IIRC, my measured noise was about 300mV.

Using the Ishikawa IPS boards, it is possible to build a faithful clone of the M2.
It’s also a lot of fun to try the other front ends. Surprisingly enough, there are noticeable differences. The M2x is a worthy project to take after the ACA.

There is a brave man to comment on the operation of the amplifier from the maestro?

One problem reviewing a DIY amp built by another person is that you don't know if amp is 100% up to spec. There are some of the findings in the review that makes me think it is a faulty amp/power supply.
I went to see what this website had to say—it's not worth the time. My impression was that the author didn't listen more than 10 - 30 seconds.

I dont think you need to listen for more than a few minutes to realise there is a lot distortion.
It's certainly not nasty sounding distortion and combined high Class A bias lends to nice organic sound but its very obvious if you are used to low distortion.
A cold and harsh sounding amp that still manages to measures very well may be less pleasant to listen to but I think this kind of amp is still letting you hear more of the music and less of the amp than something like ACA.

Build one of each and listen to both. Pick the one that gives you the greatest pleasure. Don't be shocked if someone else makes the other choice. Their pleasure is not necessarily identical to yours, and vice versa.
If it were only that easy. After the ACA's I built two more of Nelson's designs. I can't give up any of them.
When I recommended "build one of each", I had in mind an ACA and another amp whose sonic description resembles the attached quote. A cold and harsh sounding amp that still manages to measure very well.
