Lamm 2L Reference vs CJ GAT


Just wondering if anybody has a chance to compare the two pre.
I have L2 Reference.I am using it with Lamm LP2 and Lamm M2.2 . Lately I am a bit annoying with the lack of remote control. So I have been playing with the idea of changing the preamp. Also, I could use an extra input more than one direct and 2 line inputs on Lamm. I can't find any information on CJ input impedance to see if it might match LP2 3500 ohm output impedance. Pre to power should not be a problem, impedance wise.
I already ruled out ARC Ref5, heard the 40th Anniversary Pre but I prefer something with slightly more tubey sound rather than ARC neutral, somewhat leaner sound. My local dealer should have one to try soon but will be awhile before it is burned in properly.

thanks...that is good to know. i really, really like the Amperex 7308 (US white label) in my Zanden...much better than 2 different Mullards, JAN Phillips and Sovtek that i tried.

If i go GAT, i will remember that. i have heard very positive things about Sieman CCa, btw.
Since I have a good selection of 6922, GAT is definitely very tempting. If you can't find pinched waist Amperex, Mazda is pretty good alternative. Kind of a compromise between Mullard and Telefunken, in a way. But Pinched waist Amperex has much better extension at both end than any tube I tried with robust, full body sound not so soft or overly warm and mellow like Mullard.
