searching balanced Tube preamp with.......

That is very low for a tube amp but the Lamm L2 Reference is 130 Ohms. The McIntosh C1000T is about 220 Ohms. Both are about $17,000.

How about the ModWright LS 36.5, output impedence of 110 ohms?

Wow - that LS36.5 looks really nice for the money. Very impressive circuit design. It is interesting that they use output transformers (in a preamp) to get low output impedance - I think that is what Lamm does too but I am not sure about the McIntosh.

thanks guys.

Modwright I think is not balanced.

So far I also found Graaf gm13.5B with 90 Ohms
and Messenger with 50 ohms.

keep it coming.....
