Speaker upgrade...

The HC version of the Radian means High Current, requiring a high current amp like the Spectral that they were designed with.

After hearing them at a top dealer in a couple of ~1hr. demos, I fell in love and eventually bought them along with Spectral & MIT gear all made to fit each other, similar to the famous "2C3D" system reviewed in Stereophile. At home in a professionally setup room, this rig bored me so much I couldn't wait to replace it with something less detailed but more rhythmic and musical. Moving to Quad ESL63s and Cary tube amps was probably an overreaction in the opposite direction, but the latter pair kept me smiling in the listening room far more than the Radians did. Cheers,

"you will never achieve real audio you will always be changing your equipment and wasting your money because that is what the corrupt music reproduction system industry wants you to do for their profits only."

I agree, most of the hi fi industry makes "cosmetic gear" components that design to attract the unprofessional listeners and make the W A W factor on potential naive consumers by making a false manipulation on the sound ( artificial coloration, exaggerate dynamics act.)
You should avoid this gear at all costs and choose components carefully base on their faithful reproduction of the original recording and not on your personal subjective preferences.

I'd agree with audiotroy above about looking at newer designs, as speaker driver technology has just advanced so much since "back in the day".  I'd also agree it's hard to beat the Legacy FocusSE in overall performance at its price.  You get the Air Motion ribbon tweeter and quality bass down to 18Hz.

Thanks for all the replies. I can get the Avalon's local for 2300 and the BW for 3200 plus shipping.
