I moved away from tubes into Spectral DMC-30SV and DMA-400 this past summer. The results are fantastic. All my cables were changed from Transparent to MIT. No problems with hiss. I did have to add a few ferrite beads to my phono cable, but it was because of a new Sutherland PhonoBlock. I ran the 30sv with VK-150SEs until the 400's came into the picture.
Spectral Owners, Are you staying Spectral Loyal or leaving the brand behind?
Spectral requires you to use a Spectral preamp and MIT cabling. I followed this path for 20 years. Some have used other equipment, Preamps, cabling etc. I found that Spectral would Not, Play well with Others. I waited 6 months for a 30SV preamp. It was "Magical". I ordered a pair of DMA 400s. The next day, the 30SV stopped playing well with my Manley Steelhead. Then my Pass XOno. I tried everything Alan Goodwin recommended, including an expedited trip to the factory. After 2 months, I gave up. Sent 30SV back for full refund, cancelled order for DMA 400s. Bought Pass Lab electronics. System is Happy and so am I. I still miss the 30SV. I am waiting for the "Mythical" Spectral dedicated Phono stage for 12-13 years now. I am a vinyl guy. I have heard the Spectral CDPs. They are wonderful in a Spectral system. But I am a vinyl guy. I am certain if the dedicated phonostage is ever finished, it too will be an awesome piece of equipment. What are loyal Spectral owners doing?
