from several reasons I'm always posting Fugly! as fookin' ugly ...... take it as " that's really ugly , I don't wanna to have something like this , I can make something like that with one hand behind my back etc. "

shortly - that's just expression of my envy




(for critical places you can use MOX resistors - there 3 pcs 2K2/1W in parallel )

I take "fugly" as a Trade mark of Quality. Not necessary a beautiful build. But of great quality.

We can make a suggestion for the new English dictionairy 2010 but our English friends are quite conservative so I'm afraid ...

Thx Jacco,

I'll have a look again.

I have seen very beautiful "mini mox" from Ohmite (medical/space quality) but couldn't find a supplier.

joho,

Great looking amp, and getting a report of its quality is even better. Nelson commented to me that it looks very simple, but has some tricks that make it a good amp. Now we have some confirmation.

Those interested in boards should continue to post here..

[Tea-Bag]

I am certainly eager to get my hands on the front end boards for BA-1 and 2.

[Skip Pack]

I may be on the list or not. I have a chassis from BAF 2008 with
4 complimentary pairs of IFP230's per side. I expect I would need
the front end and bias boards, but not the outputs. From earlier
in the BA2 thread, there was mention of matched jfets for the
front end being available. Is that still a possibility?

thanks,

Skip Pack

Hi Variac, thx for the response.

The big advance of the BA2 is it's flexability. I don't want to repeat the details as you can read in Nelson's document but for me it was the reason to give it a try. Also the modulare setup is a point. It's easy for me to change the VAS.
I'm 100% sure it sounds very good. Does it sound better than p.e. an Aleph5 or the well known AX? I don't know. I have an excellent sounding A5 but it has a different supply(dual mono),other main caps, other filter coils, other wiring etc. so it's very difficult to compare.
Both amps sound very good but slight different. Some tracks I like best playing on the A5 others on the BA2.
This afternoon I changed my digital source(Rotel RCD990)to a Cyrus CD8SE and I was so impressed by the sound of the system that I couldn't hit the stop button. I was complete "in the music". The power amp was the Aleph5 and I had no time left to change to the BA2. That's life.
It take a lot of time to do serious and objective listening sessions so after a few weeks I can tell more.
