DAC/Preamp Advice Please
« on: March 12, 2015, 10:25:58 AM »
I know a lot has been asked and advice already given regarding DACs.
I want a DAC/pre combo that I can run my AVR through- and to match with my Hypex (Class D) monoblocks
I bought a Fostex HP-A8 which arrived damaged. I have looked on the internet at very many options.
Audiotining is the problem.
I will have a Perreaux Audiant DP32 for the weekend- around R20k
 Specifications (abbreviated)
Digital Inputs:    1 USB (asynchronous 24/192)
Digital to Analogue Converter:    ESS Technology Sabre³² Reference ES9018 32-bit DAC
Input Word Length (maximum):    24-bit (AES/EBU, Coaxial, Optical) 24-bit (USB)
Input Sample Rate (maximum):    192kHz (all inputs)
DAC Output Voltage:    2.0Vrms @ 0dBFS
Total Correlated Jitter:    <10ps @ -3dBFS (all sample rates)
Volume Control Bypass:    Yes (selectable)
Maximum Output Voltage:    12.0Vrms
Analogue Output Impedance:  Balanced XLR 100Ω  Unbalanced RCA 50Ω
Total Harmonic Distortion (THD+N):  Typically  20Hz to 20kHz 0.0005% @ 1kHz better than 0.001%
Frequency Response:  20Hz to 20kHz    ±0.05dB
Signal to Noise:    140dB, ref. 2Vrms (unweighted)
Dynamic Range:  140dB @ -60dB, ref. 2Vrms (unweighted)
Channel Separation:  20Hz to 20kHz    better than 115dB, ref. 2Vrms

I am also very interested in a Jolida Fusion DAC/pre- with or without stage 1 mod.
No chance of auditioning though...
Jolida Fusion
Max Output voltage:             2.8 V
Voltage Gain:                        10 dB
Frequency Response:          20Hz – KHz, (+/- 1 dB)
SNR:                                       > 100 dB
Distortion THD:                    Less than .02%
Input Impedance:                  100Kohms
Output Impedance:               47 Kohms
Tube Complement:               2 pcs. 12AX7
Power:                                    220 – 240 VAC, fuse 5 x 20 mm 0.5 amp slo blow
Power consumption:            15 w

DAC Specifications: USB: 24/96 up sampling to 192 Hz, Toslink and coaxial: 24/192HzD
Galvanic Isolation: ADuM 1250 chips
Asynchronous Burr Brown Chip AD1896
DAC Chip: PCM 1798
All signal inputs are isolated
DAC chip directly transmits analog signal to SRPP Tubes
Bluetooth Frequency: 2.4 G, Bluetooth V2.1 + EDR , Aptx codec
Bluetooth maximum reception distance is 35 feet.
Upgrade I: Resistor, diode, capacitor and tube upgrade.
Without the upgrade the Jolida is a few R1000 less than the Perreaux, otherwise a fair bit more since the rand continues to nosedive

Anybody heard either? Any suggestions?

I should announce an option in the next few days.
