SS Preamp with Balance Control


Any recommendations for a high end, solid state preamp with a balance control? I have a difficult room, and a balance control would be useful.

I have one in my system, replacing a Modwright 9.0SE and a Conrad Johnson 16LS before that. No complaints. Leave it on all the time. Not your typical SS pre if you like the sound of a tubed pre.
I should have added that whatever preamp I get will have to partner well with my amp, a Burmester 911 Mk3. The Burmester has a low input impedance, which affects choice of a preamp. I'm presently using an MBL 5011, and have thought of either a Burmester 011 or an MBL 6010D, but neither of them have balance controls. My room, 32 x 14, has a large, open arch to another room just a few feet from the left speaker. The right speaker has two walls, one behind it and another alongside, but the left speaker only has one wall, the one behind it. As you can imagine, this makes for an audible difference, particularly on some CDs. Hence my interest in balance control. I have ten accoustic resonators at various locations, and they help, though not enough on some source materials.
I had a Pass X2.5 the bal worked fantastic, quick for A-Bing, and the output impedance was designed for Pass imput impedence of 22 kohm. They are great looking and built like a tank.
Kusina, the Capri has an output impedance of 80Ohms in balanced mode. The upcoming battery powered JRDG Criterion's output impedance in balanced mode will be even lower: 60Ohms. G.
