Seems to show that thick isn't always better and looks aren't everything.
I've been using off-the-rail 1.9mm silverplated teflon coaxial as internal wiring for ages, the reason i don't use it externally is because it looks so whimpy.
Wondered myself many times why pro manufacturers take such a risk by cabletieing inputs and outputs for cosmetic reasons.

Jozua, i take it the MKII refreshing was well worth it ?

Now excuse me, a whale is supposed to have grounded at the beach.

My doc just told me that smoking is bad for my WIKI.

Hey caveman,

My analyst told me its best to relieve my stress and not let it build up, so often I go to the beach and club baby seals

If it wasn't that the original <2mm diameter interconnect wire was also cable tied tight I wouldn't have done it with the new vdH one, but since the vdH is almost 10mm thick and it makes an unappealling curl when left untied I did it.

I do have my doubts about using a balanced cable for unbalanced purposes, and I think that by shorting the braid to ground at both sides or even just the other may change things.

The amp is beginning to show it's true colours. Very smooth non-aggressive sound.

If this is the effect of the Black Gate caps then I am sold on them. In the KSA Mk1 they made a reasonable difference but in the Mk2 amp they truly sound exceptional.

For the moment the Mk1 still has a tighter bass than the Mk2 but this is only after about 20 hours of playing with the new caps.

the improvement is more probably due to the upgrade to the MJ21194/21193's from the 15003/4's than the BG's IMO.

I tend to agree with you on that. I've used BG's in a couple of past projects with no real audible difference between them and $2.00 caps. I used the same devices in mine but wired it with silver plated 12 ga stranded/ teflon covered. Have always used this wire in past projects and it does make a huge difference. My KRell sounded excellent fomr the minute it was turned on... I cranked the bias up to 575mv from 300mv last night and it just gets sweeter and sweeter sounding. Absolutely amazing!

Jozua... You need to can the SS line stage and build the 12B4 to really hear what your KSA-100 is capable of, I would say the SS line stage is more your limiting factor at this point. I had a similar Krell KBL line stage and the 12B4 is miles and miles ahead of it.

Please send me info on the 12b4.

The output devices were also rewired with Van Den Hul CS16 wire which I believe is silver coated high grade copper with a teflon covering. The orginal wire was real cheapo.

Please contact me privately at hugot@icon.co.za. There are other issues I would like to discuss off-line.

Thanks.

Hi, do a search with: Yet another 12B4 line stage.
Goodluck,Loek

The 12B4 thread is here. . The reason I bring up the 12B4 is because I've been down the Krell line stae road already.

Mark,

Do you update the WIKI regurally with payment information. i have sent you 50$ for 2 boards some week ago and have no idea if you ever got it.
