Suggestion used tube amp between $1,500-2,000

The input impedance of the RM-200 is 30k via it's XLR inputs, I believe.

Thanks bdp24. But note that the LS7 preamp only provides unbalanced RCA outputs. And using an adapter to put the unbalanced signals into the amp’s XLR inputs would most likely still result in the LS7 seeing a 15K load, as the 30K figure most likely reflects the sum of the impedances of the two legs of each of the balanced inputs.

would manley stingray be powerful enough? cary sli80 used ...both around 2500...

I'm getting cronus magnum 2 for 88 db totem sttafs...

usatubeaudio swears by ayon it seems, more poewrful than what I needed and pricey new...

jolida, cayin used would be easily below 2k...


I mean I hardly know what I'm talking about tho...just got into this...

Nighthawk MK2 integrated amp by Raven audio for $2600 new.  Check it out.  Call the owner, Dave and he will be a tremendous help to.  I agree with the above posters on going the integrated amp way.  

Ah yes Al, unbalanced only on the LS7. Of course, if Eddy goes passive, he could get a passive pre with balanced out. They are available, aren't they? Not that Eddy indicated any dissatisfaction with his LS7, but when I see a system with a single line level source, I think passive pre. Roger recommends that route with the RM-200. An even better course of action, if the source allows it, is to install an attenuator right in the source component. No impedance match to worry about, and one less interconnect! Ric Schultz of EVS used to make a great attenuator, of discrete resistor-ladder design. VERY transparent.
