I think high quality copper can make a difference towards the top end , more than anything. I notice Cardas make & draw their own copper for instance. Litz wire sounds v.good to my ears in the HF, and when the strands are below 40ga is supposed to be almost like single-crystal, so my transformer...

Yum !

This seems like the right thread on which to post some links from Klaus's site ( 'Russian tube tester' ) : http://www.klausmobile.narod.ru/projects/pr_01_mamont_e.htm And this driver stage for a circlotron , using DHP's ( 4P1L ) looks rather tasty : http://www.klausmobile.narod.ru/projects/pr_09_seo...

I don't think satellite cable is much good . Perhaps OK as a bass-only cable. The CAT5 recipe I've heard was this one : http://www.tnt-audio.com/clinica/ffrc_e.html and it was very nice. I think it would be difficult to beat for less than £300 . There is substantial discussion of Tellurium Q cables ...

Sad to see him go, what a massive contribution he made to astronomy . I read a couple of his books early on - and astronomy and telescope making is what got me into optics. The programme was great - stubbornly old-fashioned, no dumbing-down at all, and packed with content every month . Hopefully the...

You guys haven't got a chance against someone like myself - you're just amateurs

From what I heard of the 'Black' , it was different to the other cables I was able to compare against . It seems to be a very good mids and bass cable to my ears . It didn't quite have the treble finesse or treble tone that I was able to get from the ( cheap ) litz/cotton Bud Purvine specials, or th...

The old cast aluminium ones do sound the best though, don't they ?

Hello Chaps Dug out of my drawer of cartridges ... not required .. Nearly new Denon 103 , bought late 2008 . Used on two occasions to do comparisons against 103R , once in late 2008 with some experimentation with loading/weight , then again recently on the jFET phono experiments . Total usage unlike...

Wow that's a funky looking amp ! - excellent .
I should make more silly suggestions like that and see what great stuff people can come up with . I assume it's going to be known as the BBP pre-amp ?

I played the first album only a few days ago, fabulous debut, sad to see a great guy go that young.

I suppose it's a combination of my experiences on the Aurora project, plus things Bud has said, and Owston experiences & Nick's efforts on tweaking Richard Cooper's AN amp .
If you don't drive them enough you seem to lose the low level stuff and hence the transparency.

Good to see 35mA driving that interstage, Paul .
I reckon you need at least 20mA to drive ANY interstage, regardless of what the specs say or how small it is .
Interesting circuit .
When did you come across the PL84 ? - never heard of it before .
