Had fun loading my QP1R the last couple days. Looking at file sizes. Max so far is The Cars debut album 192/24 FLAC, sounds awesome but almost 2.5 GB!
Grappling with the ALAC versus AIFF debate this evening. Re ripping CD's from my collection using iTunes. Both Lossless formats and can't really say that I hear any difference. The AIFF albums take about 0.6GB and do not involve any compression scheme, the ALAC (Apple Lossless) albums take up only 0.3 GB so roughly half of the AIFF file size, but the QP1R has to work to decode (unzip) the ALAC files, so in theory that could degrade sound quality or battery life due to the processor load. Anyone? Bueller? Bueller?
Well, I have been using the QP1R for 6 months now and I have not seen any deterioration in battery life so far. I store all sorts of file formats from AIFF, WAV, FLAC, APE, Mp3,DSD-DSF-DFF,SACD and it makes no difference. The only thing I've noticed is with some of the APE albums, there is a processing delay, but later I ripped them in non APE formats like WAV/ALAC/FLAC and they seem to work fine now.
Now on a different topic, the best sounding albums I have listened to through QP1R so far, consists of albums in various formats, here are the following:
1. Good People in Times of Evil (APE) [Jonas Helborg, Shawn Lane, Selvaganesh)
2. Jazz at the Pawn Shop [DSD 128]( Arne Domnérus, Bengt Hallberg, Lars Erstrand, Georg Riedel, Egil Johansen)
3. Over-nite Sensation/Apostrophe [DSD 64] (Frank Zappa and The Mothers of Invention)
4. Hand Cannot Erase [24 Bit 96Khz ALAC] (Steven Wilson, Marco Minnemann, Guthrie Govan)
