NORMA Amps

The SC-2 and PA-150 combination are something very special indeed.
Definitely give them an audition if you can. Personally not a Spectral fan, so there is indeed a difference. The Normas were more refined in practically all areas in my trials.

Haven't heard them but wonder about cable recommendations. Spectral demands their components be used with MIT, or else the warranty is void, I strongly suspect due to bandwidth limiting so the components do not go into oscillation.

On the other hand I have some audio cables capable of transmitting hi-def video (74 MHz) without phase shift.

Just by the build and parts quality Norma 2Mhz deserves more North American interest. From what i've read they add more "body" to the music then Spectral Audio while maintaning speed/detail and lack of coloration. The distributor TMH needs to get the glossy "rags" to review their products and have the gear available at audio shows. It's unfortunate that many well heeled audiophiles need "expert" approval when purchasing audio gear.
