![]() ![]() I would be interested in hearing opinions about this. If I used an LPS for the SPDIF iPurifier I would also move it to circuit (3). Each of these has its own power conditioner. I'm very careful about power and have separate circuits for (1) hardware with SMPS (Macbook, hard drive, Apple Airport Extreme, and iPower), (2) power amps and (3) all other source components. I would like to ask if you believe the iPower 5 volt SMPS which comes with the iPurifier could be improved upon by a good quality (in the $500.00 range) LPS? The improvement was far far better than anything I heard by using any USB decrapifier, and I've tried many (the ones I mentioned above are just what I finally settled on, although I never tried any iFi USB products).īut I'm an audiophile and so anal (by definition?). The soundstage expanded, the music became far more 3 dimensional. I didn't expect much from the iPurifier because I thought my SPDIF signal was pretty good to begin with, but after plugging in the SPDIF iPurifier I was shocked by what I heard. My SPDIF chain has just been a Cardas BNC to RCA plug adapter and a very well made RCA - RCA plug SPDIF cable (locally produced in Calgary Alberta, by Moray James), which compared well with cables costing thousands of dollars made by the "big boys". By the way, in order to have my USB sound quality to nearly equal SPDIF I needed 1) the quad speed MSB USB module 2) iBooster VBus isolator2 3) Wyred 4 Sound USB Reclocker powered by a iBooster LPS and 4) a Curious cable link/LightSpeed Harmonic cable (so lots of USB tweeks). I only purchased it on a whim because my SPDIF sound quality has always been slightly better than my USB sound quality. I received my SPDIF iPurifier three days ago an placed it between my Bryston BDP2 (with the latest IAD board) and my MSB Analogue DAC.
