BEST BALANCED XLR TUBE PREAMP FOR JC-1 MONOS?


Hello all,
I am wanting to experiment with tube preamps for my JC-1 monoblock amps.
Here are my requirements:
1. MUST have balanced XLR outputs.
2. Remote control preferred.
3. Would like a headphone jack.
4. Would prefer Class A, dual-mono, all discrete circuitry.
5. Must match up extremely well and have exceptional synergy with the JC-1's.
I want it to retain ALL the sound qualities of solid state preamps such as top-end extension, detail, transparency, dynamics, speed, bass power and extension, etc., while adding the dimensionality, staging, and "air" of tubes.
I do not want one that is the least bit rolled off on top, laid-back, too euphonic, warm, or rolled off or spongy in the bass.
Some balanced tube preamps I have heard some good things about are the Aesthetix Calypso, ARC LS25 MK.II, Sonic Frontiers, etc.
I want to hear from people with first hand experience only.
Thanks for all your help and answers, everyone!

I'm using an Atma-Sphere MP-3 with JC-1s right now and think it's a great combination. I am a dealer for both. If you go with the MP-3, be sure to opt for the regulated power supply option. Sonically it will meet your criteria, but it does not have a phono jack or remote. Some people find the discrete-step resistor ladder volume control a bit clunky, but it's a very high-performance solution.

The Atma-Sphere MP-1 would be even better, but is quite a bit more expensive.

I have a couple of tube headphone amps on order, but until they arrive my headphone experience is limited to preamps with headphone jacks and a Headroom maxed-out home unit, and the Headroom was definitely better.

Suggest that you check out the Einstein preamp. No headphone jack but otherwise meets all your requirements and from personal experience, I can say that it mates extremely well with the JC-1's.
Thanks for your responses so far!
Just throw the headphone jack option out the window, since very few preamps have one anyway.
I was just going to recomend the preamp you already have even though it's not tube. I love the Ayre K1x with my JC1s, and felt like it's addition was a huge improvment to my system. I had the CJ 17 before and no balanced outs, so it may not be a good comparison. I will be very interested to hear how your new preamp works out since you are using the same gear now as I am. If you can deal with the price, I would check out the VTL 7.5, also I think the Calypso sounds like a good idea too. Keep us posted on how things turn out, and good luck girl.
