Spectral DMC 30SS& DMA 250, need advice

My apologies Keith, I see your point of course.
Teddy, I am not familiar with those cables. the SC's are nothing to worry about, it is the IC's Spectral is warning about. If I were in your shoes, I'd try those IC's softly at first at low SPL and see what happens. Probably nothing, but then you can never be sure. Maybe follow Keith's advice after all, or get in touch with Joe Abrams of Equus Audio. He advertises here on A. He is very kind and helpful. Give him my regards and say I sent you.
Cheers,

Thank you vey much, SC is what I worry about. Spectral has special filter inside SC network.

I had hoped someone other would have taken this up, but then:
Teddy, These networks MIT uses to voice their SCs with. But then you can use any other decent SCs with your gear, as my experience has shown. I had used MIT but also NordOst. If in doubt, ask Joe, as I had suggested before and give him my regards.

Hi Detlof, I have send an email to Joe on =ct 28th but haven't got answer yet.

Hi Teddy_bear,
I have been using PS Audio SC series PC on my DMA 100S amp for several years based on advice that Rick Fryer does not recommend networked cables on amps. On the SDR 4000S and DMC 30SL I use MIT Z II plugged into MIT Iso Duo isolation device. There is also a Z Stabiliser plugged in next to the amp. Remember to think of all of these components as part of a coherent system. Mix and match with care! Enjoy your new amp/pre they are as good as it gets!
