I doubt there would be a significant change in the "voicing" of the amplifier this is more than likely a production change due to availability or a new contract they got from Rubycon. 22000uF compared to 25000uF will not make a significant difference in ripple, what it will do is reduce the current drain/sag from the transformer and that is more of an issue with regard to sound quality and Power Supply performance.
Parasound Halo JC-1 factory capacitor change
A pair of brand new Halo JC-1s arrived at friend's place a few days ago..
Being invited to help my friend to lift two huge boxes upstairs, I was also curious to see interiors, and to make a few pictures of the JC-1s internal layout if possible. We easily removed the top cover, seeing a perfectly clean, obviously brand new unit inside. What surprised me quite a bit (owner seems to be not too concerned about) was the change of four main 33000microF capacitors: original 33000 100V Nichicon caps are now replaced with equally sized Rubicon CE LSQ, also 33000 microF, 100V.
Since Parasound also changed the original 25000 Elna caps with 22000 Rubicons on smaller stereo model Halo A21 (there is a related topic on another forum), it seems that this is a deliberate manufacturer's policy rather than, say, discontinued production of original parts by suppliers (Nichicon, Elna etc).
I am pretty seriously concerned with this issue, since I consider purchasing a pair of new Halo JC-1s as well.
Anyone else out there spotted this internal change in the Halo JC-1? Any impression listening the new cap version JC-1 versus original? Could actually main capacitors bank affect sound seriously..??
tnx
