AudioCap is a trade name for a line of audiophile caps that are manufactured by RELIABLE CAPACITORS . Their UK representative is "Audio Com" who can be emailed at [email protected] . Get them to quote some prices to you , including their delivery times . If it seems the caps having to be shipped out from California then consider checking out Parts Connexion who sell Reliables' other 2 lines' of caps. These other 2 lines are "MultiCap" and "RelCap" . Parts Connexion is a Canadain eTailer ( Toronto based ) .

I'd be very wary of just replacing the bypass caps and expecting instantly positive results. For Instance; The reason I asked if the existing bypass caps were MKT or MKP ( or MKC ) is: If MKT was used , they would be present to blunt the edge or round out the typical "edgy" signature of the electrolytic. The necessity to include MKT would imply to me something about the sonic signature of the Elna(s). MKT , unfortunately doesn't offer great depth or resolution - just a "masked rounded" quality. MKT is Metallized Mylar ( MKP is metallized polypropylene & MKC is metallized polycarbonate ) . If MKP types are present , they would suggest that the DC-biased Elna(s) are not as edgy as most typical electrolytics. That would signal (me) that they might be able to be left intact with just higher quality Film & Foil bypasses shouldering the resolution burden. MKC has qualities that combine attributes from both MKT & MKP .

Base Caps - replacement

Space limitations could dictate that you might have to replace your electrolytics with "Metallized Polypropylene" caps . Smaller physical size was the driving force behind the development of all types of "metallized caps". Eliminating the separate foil layer ( by vapour depositing ) metal directly onto one or both surfaces of the plastic dielectric creates a "metallized" dielectric capacitor . Smaller size is the only "real" benefit for this type of cap. All the current cap makers are trying to construct MPP types that sound as good as a plain old "Film & Foil" types .

- Giskard has already recommended Solen - "Metallized" ( the second post of this thread) and then went on to later mention that the 250ti(s) developer ( from JBL ) has used Solens in his Charge Coupled Networks. Giskard has also stated that what is released to the public isn't necessarily what those who know better will use them themselves. Does more really need to be said on this ? I'd add, that you should stick with the smallest Solens available - the 250 volt variety . Also, I don't believe "Axion" MPP(s) will be much different with these transducers. I'd buy whatever type is most available to you.

ps I wouldn't let all the recent "yellow-flags" over replacing your NP electrolytics deter you from pursuing better resolution.

thanks for that, I have just had another look inside the network and found that the big blue capacitors have ELYTONE and are 100V np and the small ones have MPR .01K 250V CMC . with this information, would you still reecomend changing only the bypass capacitors and of what make and value. How many bypass capacitors are there within my network?.
Many thanks.

PS: where can I get my hands on the network diagram.
