Hmmm....??
Wonder what cables and/or what equipment you are listening to. Even my +80 old parents, who are not audiophiles by any means , hears the difference!

Well until a couple of months ago I could hear the difference between cables, but I didn't think the differences were very large.

But now..well, I shocked myself. I'll be writing it all up soon. But one telling thing was when I demoed the new interconnect against my old one to a friend. His first reaction was accusing me of cheating and playing a different version of the same song.

You know, some people think amps all sound the same

..or that chipamps sound great...(but let's not go there)

Very interested in another approach - I was a bit surprised at the difference that Cryo treatment to some silver interconnects made to the sound - more noticeable that double annealing and that was quite apparent.

JH: This is something I mean to try sometime. I've found a place locally that can do cryo treatment quite cheaply. But save this please for my new upcoming interconnect thread. I'll be sure to post links to it when I write it all up. Thanks.

I haven't built my Mozzie yet - still getting things together - is there anyone over here in Melb that you know has finished one?

Looking forward to this new IC.

Audience Auricap polypropylene capacitor 0.47 uF @ 400V | eBay

13.95 a piece for the 400v version.

or should i spend just a little more on the 600v version.

cheers

I am using the 400V variant. THIS IS WHERE I GOT MINE

Same with those goddamn Vishay resistors that cost almost $10 each.
Even if you build with budget parts it will still blow the pants off just about every other amp.

Thank you.

i have a terrible hum but only 1 channel connected now.

i used steel btw instead of aluminium for the housing, i know this is wrong but could this be the cause of the humm?

besides the humm it sounds great, though the highs are a bit harsh.

[dvh99]

the humm does not get louder with increasing volume.

200mv across the source resistors (0,2ohm) 2pairs buz900/905 per channel.

where did you take the speaker ground to?

Mine go right to the "0"V on the MOSFET PSU cap bank. 1 ground wire from there also goes to star ground point on chassis. IEC Inlet to star ground point and 1 wire from Aikido board to star ground.

Mine is absolutely dead silent.
