Olen vihdoin innostunut Spotifyn käytöstä ja setuppini on seuraava:
- iMacilla pyörii spotify (unlimited)
- Airfoililla ääni wlanin kautta AirPort Expressille
- APE:lta optisella Harman/Kardonin AVR 230 -viritinvahvistimelle
- Digital-to-Analog H/K:n DAC:illa
- Kaiuttimina Amphionin Helium 2 setti + Choruksen Vertigo XLS
Audiosettihän ei ole mitään referenssilaatua, mutta silti mietin, josko ulkoisen DAC:in lisääminen toisi äänentoistoon lisää potkua/syvyyttä/väriä.
H/K:n service manualista löysin seuraavat tiedot AVR 230:n DAC:ista:

AK4358
192kHz 24-Bit 8ch DAC with DSD Input
The AK4358 is eight channels 24bit DAC corresponding to digital audio system. Using AKM's advanced
multi bit architecture for its modulator the AK4358 delivers a wide dynamic range while preserving
linearity for improved THD+N performance. The AK4358 has full differential SCF outputs, removing the
need for AC coupling capacitors and increasing performance for systems with excessive clock jitter. The
AK4358 accepts 192kHz PCM data and 1-Bit DSD data, ideal for a wide range of applications including
DVD-Audio and SACD.
Sampling Rate Ranging from 8kHz to 192kHz
o 24Bit 8 times Digital Filter with Slow roll-off option
o THD+N: -94dB
o DR, S/N: 114dB
o High Tolerance to Clock Jitter
o Low Distortion Differential Output

o Channel Independent Digital De-emphasis for 32, 44.1 & 48kHz sampling
o Zero Detect function
o Channel Independent Digital Attenuator with soft-transition (3 Speed mode)
o Soft Mute
o 3-wire Serial and I2C Bus µP I/F for mode setting
o I/F format: MSB justified, LSB justified (16bit, 20bit, 24bit), I2S, TDM or DSD
o Master clock: 256fs, 384fs, 512fs or 768fs (PCM Normal Speed Mode)
128fs, 192fs, 256fs or 384fs (PCM Double Speed Mode)
128fs or 192fs (PCM Quad Speed Mode)
512fs or 768fs (DSD Mode)
