Dpac996, you have compared 1 relatively inexpensive ($1400) switching amp with SS and tubed devices ranging in price between $5000 and $8000 and found the $1400 amp to be wanting--not an overwhelming surprise. You may have wanted to compare the fine amps you enjoyed with switching devices in the same price range. You may or may have not enjoyed the Spectrum, Nuforce, or JRDG Continuum 500, but at least you would have derived meaningful findings.

I love jeff Rowland's implementation of ICDPower in his 501, 312 and Continuum 500 integrated designs, all of which I've heard pretty extensively. I've had single-ended tubes, class AB tubes, class AB SS and now my new Continuum 500. I can't imagine anyone listening to my system and saying, "It doesn't draw me into the music."

I'm a trumpeter for fun, playing in several orchestras and bands and attending many more concerts as a listener. I look for real musical sound, without added bloom or mid-range euphonics. The Continuum 500 delivers dynamics, transparency and pure sound that sucks me in every time I turn it on.

I'm obtaining excellent results from a PS Audio HCA-2 amplifier driving Acoustat 2+2 electrostatic speakers.

I bought a pair of BC Ref1000s to have a listen to and ended up keeping them and selling the in use Pass x350 I was using at the time. (Meridian 861 and Revel Studios + treated room).

Wouldnt go back.

Hi Vikingboy, what did you like in the BC Ref 1000 over the Pass X350?
