Caro S. Rossi:
I discovered this interesting thread independently of my interest in RWA – I was actually doing a search for “SLA powered dac”. The Isabella concept brings up some thorny questions, but first a digression:
RWA appeals to my personal ‘less is more’ approach and I am contemplating being weaned off the perpetual pursuit of warm bottles in favor of the cool logic of tri-path. The 21st century has shown – through the likes of Bel-Canto, PS Audio, Nu-Force, Nelson Pass, et al., that music can be made with the intermediation of solid state – and you are certainly on the leading edge of these developments. (Likewise, Emission Labs and KR Audio have brought full range to SET.) As a musician, 2 main areas of concern for me, in reproduced music, are: dynamic range and bandwidth. And, while I love vinyl and tubes (and believe they have the edge in ultimate musicality) – if I may be so bold: digital trumps vinyl handily in these 2 parameters; while solid state (done right) wins over tubes to a rather lesser degree. So here I am, a collector of NOS dacs (4, and counting – of slightly varying flavor) with 125+ gigs of lossless music, and looking for only 2 things: the ideal single input amp for my 98 db speakers, and a battery powered (NOS, of course) dac with multiple digital inputs. So, while you will likely come up with a beautifully rendered tube circuit, the real question for me here is: might you consider offering the dac as an option inside the 30.2 (a supremely elegant solution and, I believe, true to the RWA spirit) – or, offering a stand alone SLA powered dac?
Thank you for your consideration of these ramblings. Saluti, David
