You're already in some pretty thin air, and it looks like your streamer is the next thing I'd consider upgrading. Judging from the sales on the Node I'm seeing all over, there's a new model in the Wings. So you might want to wait and see, or jump.to an Arender or something such. Much more likely to get a bump in SQ there, rather than by swapping preamps.
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
