Output stage has 350VA to schottky rectifiers to 6 x 10,000uf caps to amp board (54V)
Input stage has 50VA (for now) to soft recovery rectifier diodes to 6 X 4,700uf caps to Avondale regulator board to amp board (47V)
It took me a while to do as this was my first time splitting the stages in a poweramp Triple checked everything and turned on with a broom handle (only joking). I was a bit nervous though. Apparently there is more chance of DC getting to the drivers if the front end is split off and it fails ..gulp.
I am very impressed by what has happened with this I put the first two completed on the mid range as I thought I would get most benefit from starting there. Next will be the tweeter monoblocs. I don't know if the bass will get done as I don't have enough regulator boards to do it but I could split them off and give separate psu's without regulators. Maybe I could swap the tweeter amps on to the bass and see if it is worthwhile there too before hassling les at Avondale for two more regulator boards.
Onward to the next two monoblocs........................
I have done some more listening and this regulated front end lark is well worth doing. I am hearing more detail for sure especially low level stuff. Listening to Chemical Brothers - we are the night I am suddenly more aware of the sound effects they have used especially on sounds which are low in the mix. Echoes of reverb are especially unlocked now. This is a highly electronic album (some real instruments on it) and of course there are lots of effects used. When a passage of music suddenly stops it drops in to complete silence but before that happens you can hear much more of the sound effects tailing off in to the silence.
Giving the front end it's own psu and regulator is like putting a velvet glove on an iron fist.
The higher NVA power amp models give the front end it's own psu but don't use a regulator. They also give the front end a big toroid even though the current draw of an input stage is usually very low (mine is 12mA). I must try giving my front ends a big ass toroid as well and try without a regulator. I can't try without a regulator at the moment because the transformers I have give me too much voltage.
Checked for continuity and all is good , no breakages on transit.
Currently hooking them up...................................
What I can say now is that as ever with NVA it is all about the music - there is more of it. It improves things over my Avondale blacklink cable in key areas.
There is more space, instruments sound more like real instruments. I have noticed some bass lines much easier to follow. There is more information present but in a subtle, not in your face way. More lovely textures to synth's and bass. I noticed the sound of a snare drum earlier which clearly was not being hit in the centre of the skin where as before it was masked. The space around instruments is clearer and decay of notes more detailed.
I will do a proper review (talking about the music) for the review thread in a week or two when any burn in will have probably finished. I like it a lot - there is more to hear but it is less fatiguing than before if that makes sense.
Busy listening to CD after CD which is a good thing
Edit - I reverted from triamping to biamping for this and it is clearly better than triamping with the old cables (not NVA amps though)
