Help in deciding which tube preamp to replace my old SFL-2


I'm a long time audiophile. I am finally admitting that it is time to upgrade my tube preamp. For many years it has been my beloved Sonic Frontiers SFL-2 which was upgraded at Parts Connexxion about eight years ago and five years ago I changed out the 6922's to Siemens Rohre CCA tubes. Still sounds wonderful, but it's time. I am exclusively a vinyl listener and my system is: Nottingham table with Koetsu Rosewood Signature Platinum cartridge. Aesthetix Rhea Signature phono preamp fed to the SFL-2 via  balanced interconnects. Primaluna EVO 400's as monoblocks with new KT88's and vintage European small tubes. I also still have my Levinson 27.5 and 23 SS amps. Speakers are Avalon Acoustics Opus. All cables are Transparent Audio Ultras. Musical preference is mostly classic rock; Steely Dan, Dire Straits, Cars, Eric Clapton, etc... but have over 3,000 LP's and do listen to Sinatra quite often. Love string guitars. I plan to buy used, and my budget is around $10K. I've narrowed it down to the following: VTL 7.5 (III), CJ GAT, AR Ref 5SE of Ref 6, Concert Fidelity CF-080 LSX V3, or an Aesthetix Callstio Eclipse.

I respect all comments, criticisms, and suggestions. Thank you.

I couldn’t possibly have asked for more sage advice

than that jjss49. Thank you, it helps put things

in perspective for me.

I replaced a CJ Classic 2 SE with the Zesto...  it was nice but the Zesto annihilated it , to put it lightly .   It is total ear candy !

I have heard lots of good things about Zesto… and a couple comments about quality control. So, what is it’s sonic character… what were you comparing it to… ?

 

Details please.

I love the Zesto, it has such a natural tone , you could say it is perfectly voiced for a preamp. Explosive dynamics coming from a jet black background. Great detail and huge Soundstage. Whats not to like? It is a great pre.

It has been very reliable, it’s on for hours every day. No issues. It did have a bad tube socket. With very high efficiency speakers there was an occasional faint noise in the right channel. I traced it the tube socket. They don’t make the tube sockets so unfortunately it was a bad part, no fault of Zesto. I sent it in, for a VERY reasonable fee George replaced all sockets with the new style gold/ceramic ones. I figured it’s in California it would be stupid to not do the ESP Power supply thats in the new units.

Before taking delivery of my Toolshed 300b Amp, I was talking to Matt about his latest preamp . It’s a DHT and promises to be the perfect match to what is a phenomenal amp. I’ll be selling the Zesto soon, but I can say its the best sounding pre I have ever owned or had first hand experience with to date. It’s good stuff.
