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.

op - why do you feel it’s time to replace the sf line 2? maybe just send it back to chris j have him check it out retube it?

cj is not balanced (as superb as they are), won’t be able to use balanced out from phono stage

arc ref series excellent, not sure it will significantly outperform a well dialed in sonic frontiers with excellent tubes in place

suggest you don’t fix what isn’t broken, your system is excellent as it is

arc and c-j pre's are beyond reproach, the companies are stalwarts and the sound is impeccable, kevin hayes' vac is also in this class

other companies may well make wonderful products, perhaps the equal to those of the above mentioned... there are many today, there have been many in the past

but one question is how durable and long lasting is the quality, and will the company remain healthy to support the product and customer going forward many years?  remember, this is tubed gear we are talking about

i suppose the specific buyer, their expectations, time horizon to keep the gear, and so on, determines how much they value a foundational piece of one's system from a company like the above
