Opinions on vintage cj amps and Teflon cap mods

I'm seeking opinions on having a vintage amp modified/updated. While I'm enjoying my conrad johnson Premier V as is, I can hear some significant differences when compared to some of the more modern amps I've heard. In my opinion, the sound I'm getting from my system is too soft, particularly the leading edge of notes and the upper base/lower mids. Decay, air, ambiance and overall musicality are great IMO. conrad johnson is offering modifications to the Premier 4&5 amplifiers which would include a new power supply and Teflon capacitors. What's crucial to me, is that I'm looking to improve the amplifiers performance, not just change it. The cj person I talked with said they've modified a couple of the Premier 4s with "smashing success". Thanks in advance for your experiences and opinions.

Does CJ offer these proprietary caps separately as parts for DIY in other makes or is this strictly for their own use in CJ model upgrades?

I would say no, as they probably believe this is part of their musical edge over other audio peers with their" own voiced" teflon caps.

Send them an email and ask - they are a very nice company.

They told me who made them (made in the USA) , however I forgot but I think it may be V caps - but as I said made expecially with cj's 12 proprietary herbs and spices so sound different.

cheers
