Mick, I agree with you until the time the A1 volume pot broke.
It sounded good and I was very satisfied.
I never stressed the ampli, I used it in a "religious" way, always
wired to my Celestion 5 speakers.
Now I discover it is not a single failure, other users complain about
a bad design. I am very upset.

I stop trusting Musical Fidelity.
I purchased the A1 for its sound AND for its quality (hi-fi products
claims).
A1 design quality is worse than many consumer products... so I am
wondering about sound quality... it is really a thorn in my side.


If you are dissatisfied with the sound, why not build something like the
Zen? You can have true class A then.

I am thinking about "Death Of Zen" project (funny names...)
See Elliott Sound Products, http://sound.westhost.com
I appreciate really much his feelings about hi-fi and electronics
projects. Take a look at the very interesting web site!


Yep - I like that site! This is an interesting one too - he has replaced
the preamp in an A1 with a more conventional one:

I'm just experimenting with a source-follower single-ended MOSFET
headphone amp, with an op-amp voltage gain stage. Its rather good but not
enough output (yet!) for speakers. :-)
