Berkeley direct to Spectral Amp?

Is it safe to use a Berkeley Alpha DAC run directly to a Spectral DMA 180? Spectral of course states that the amp should only be used with a Spectral preamp and MIT cables due to the high band width and possible oscillation. I do use all MIT cables but would like to run the BADA straight, as recommended by Berkeley. I also do not want to see smoke coming from the amp or my speakers! If anyone has the technical knowledge to evaluate this I would love to hear some thoughts.

I bought the amp just a short time ago and it had issues with the left channel so it is at Spectral now having all the transistors replaced. I had thought about selling it because of my fondness for the Alpha DAC but I think it would sound much better than the Krell FPB 600c I use now. I do not want to risk any damage to it, especially after the work that is being done but man is it a piece of work. If I could find a way to keep it I think I would get the clear top, this is turning into a sick relationship!

Is this a real risk? I just do not have the technical knowledge to know...? Any experiences or thoughts related would be greatly appreciated...

i know what spectral will say for certain. unless it is the "s" designated amps, all of their amps are only to be used with spectral preamps and spectral/mit cables. i just wondered what folks outside of spectral/spectral dealers thought of the real world risks.

thanks much for the input.

Richard..you should post a message on AVGuide.com forums the amps section asking for RH's input. He should be helpful on how he set it up.

i did post a message in his system setup area after i read your comment above, thanks. your suggestion would have been a more appropriate forum but that was the only one i found at the time. if nothing else, i found a new resource. i never really read through that site and there is quite a bit of good stuff.

Richard,
This is a link to Reference Recordings Berkeley Dac to Spectral DMA-180 direct.
http://www.referencerecordings.com/HRxSETUPS.asp

As a Former BADA DAC owner you can run the Berekely direct with a Spectral amp. A universal Spectral amp is preferred but not necessary. For safe operation Spectral recommends MIT SPK. As I stated in another Spectral thread the DMA-180 is not compatible with the standard MIT Oracle cables. The amp may have oscilation issue. Mit 850EVO REF SPK,was the last generation cable used with the DMA-180 series 2.
