Going Linear with the Caiman

[Ali Tait]

Well I was thinking maybe that output stage that Nick came up with would be very good,not cheap though,you need a pair of Sowter pp output trannies,and a pair of I think it's 6n1p's,which are cheap enough,so the trannies would be the major expenditure-more than the cost of the dac I think!

Thinking about it though,if I was to do that,I may as well do it to the AN rather than the Beresford.

[Ali Tait]

Oops no,it's 6n6p not 6n1p.

I think Nicks circuit was for differential output dacs, I'm still wanting to try one with the Sabre, it does make sense to try something cheaper with the Bdac, something which doesn't scare everybody off price wise

[Ali Tait]

Ahh yes I think you're right,I'd forgotten that.Maybe something from the Lampizator site then?

This might be good-

Maybe something like this if valves are too expensive

Could also try something based around the Pass B1

You could try it with the AN dac too if its any better than the supplied AN circuit is the main question

[Ali Tait]

Aye,that's the question!

Has anyone who's using their Caiman with a SuperTeddy based linear supply tried swapping the Caiman's reservoir cap for a 10uF film or tant cap yet? I'm interested to know if any different caps change the sound at all.

I've tried a basic poly cap and haven't noticed any change so far.

Yes, I did it this morning. Swapped out the 10,000uF reservoir cap for 2 x 10uF metallised polyester film caps. I also took out the 22R resistor feeding the +5V Dexa reg, replacing it with a wire link.

The SuperTeddy is set for exactly 16V. So far so good, it sounds very crisp and detailed with no lack of bass punch at all. I'll let it properly run in and report back later. I've left the Rubycon coupling caps in place as they sound excellent and I didn't want to change too much at once.
