@chenry I always look for point to point wired tube equipment that all the parts are easily sourced and available, there are many small manufacturers that do this. Some of the bigger manufacturers may use circuit boards that later are discontinued, so buying from a bigger well know manufacturer doesn't always mean you can easily get the item repaired.
Preamp upgrade
Hi all. Looking for some Reva or just to be told that it likely doesn’t get much better. Current preamp audio research ls-7 which was an audiogon purchase 12 years ago 550.00. Upgrade consideration ARC ref 3, ARC GSPre, Elliott Studio Arts 66-001, aesthetix Janus, audible illusion 3b, etc. rest of the system is parasound Jc 5 amp. eat c-sharp TT, McIntosh MP100 phono pre bluenode streamer and vandersteen treo carbon ct. audio quest cables throughout. I am wondering if the preamp upgrade for thousands more will provide any real marginal gain. Looking forward to the chat
