Jeff Rowland's Continumm

Spoke to JRDG today. From my conversation notes. . . The chips in the preamplification boards for Capri and Continuum, and the upscale boards for the upcoming Criterion, are OPA1632 ADSL differential in/differential out line drivers from Burr Brown TI. They have a 180mhz bandwidth, as such, strictly speaking, they are not phono modules. They are defined as hi performance fully differential opamps, but they are not opamps according to typical definition of opamps.
Noise floor is rated in nanovolts per hertz square root.
The devices are more typically used for driving high speed DAC circuits.
Bandwidth is further measured at 40mhz at 0.1db flatness.
distortion output is at 2k load is 0.000022%.
The chips are indeed very small 1/10th of an inch square. Internal topology of Capri is confirmed to be minimalistic. OPA1632 tiny geometry contribute to maintaining extremely short signal path crucial to audio performance. . . as we all know. One more desirable quality of OPA1632 is to have almost unmeasurable energy storage, which yields faster/deeper signal rising/decay, with consequential more transparent / 'blacker' background. G.

I listened to a couple digital amps,far from pleasant sounds

I disagree - based on my experience. Some suck, some rock. Which suck... to my ear, can be heaven to yours. Good design is everything....IMHO.

2 different amps,sounded pretty good at first,at least thats what i thought ,after extended listening,it was obvious sound wise that this was going nowhere,I used Legacy speakers with the amps.

Yes Coffeey, very similar experience. I also have listened to a couple of 'digital' amps that were rather underwhelming. . . I have even listened to a couple of tube amps that were quite honestly terrible, and I have heard a couple of traditional SS amps that were rather painful to bear. . . my conclusions? try not to generalize from matched pairs of bad apples, or. . . quit audio and pick up Origami.
