I have Eidolons, and had a Spectral DMA 150 amp before buying a pair of 360 mono's. The 360's are superior to the 150 in having noticeably better channel separation, lower noise, better dynamics, and better bass. The sound is similar enough that, without experience with the system, you may not notice the differences at first audition. The price on a used DMA 150 is far better than for a new pair of 360's. If you choose Spectral, I'd recommend checking out MIT's Oracle speaker cables; MIT's newer lines are some of their best yet and work well with Spectral/Eidolon.
Amp for Eidolon again
I know this has been somewhat covered before, but I was wondering if anyone with hands on experience with the Eidolons could advise. They are currently being driven by a pair of BEL amps rated at 200w at 8 ohms.The spec sheet for the amps does not give output into 4 ohms, but it gives a spec of 400w into 1 ohm which leads me to believe that the output into the Eidolon's 4 ohm load is considerably less. Don't get me wrong, the speakers sound very good and are extremely detailed and resolving, but I can't help wondering if I need more power to properly open up these speakers and bring out the best in them. Do you think its worthwhile to upgrade to a more powerful amp? The new Parasound JC1 is intriguing. I've also read that the Ayre V1x has enough power and mates well with the Eidolons. The Spectral 360 and Accuphase 50v are too expensive. Then there is the option to go with a cheaper high power amp like the Sunfire. Thanks.
