More discrete R2R Mulibit dacs.

George,
I`m in Europe actually.
Yes that`s exactly what I plan to do. PCM from TV to DAC via toslink.
Interestingly I didn`t find OLED`s natural also and choose Philips 8 series instead. OLED`s seem too dark and artificial no matter what settings you choose. Plasma colors are much more real. I have Pioneer plasma myself in my apartment.

George thanks but when I say implementation I am talking about the total design.  The DHT DAC that I build has a 30lbs power supply.  A little different than the typical DAC chip or R2R implementation.  Tube rectification, tube rectifier, current limiting, etc.  Most people think I am showing them a power amp when they see it.

Digital Section:
Utilizing R-2R discrete resistors digital to analog converting topology
Clock Jitter RMS: 0.8ps typical
Jitter Reduction: FIFO Buffer and reClock with low jitter clock
Input SPDIF (RCA/XLR): Up to 24 bit/ 192 Khz
Input I2S PCM (HDMI): Up to 24 bit/ 384 Khz
Input I2s DSD (HDMI): Up to DoP128 and DSD256
Frequency Range: 20 hz to 20 Khz

Analog Section:
Frequency Range: 20 hz to 20 Khz
Tubes: 101D Direct Heated Tubes for output stage. 5AR4/GZ34, 6C45pi, 101D, OC2 tubes for high voltage regulator
Tube Buffer: Full Music or Psvane 101D Direct Heated Tubes with point-to-point direct wiring, utilizing transformer coupling between digital and analog sections to isolate digital noise.
Analog Power Supply: LC (double chokes and Clarity Polypropylene TC 600 capacitors) filtering with direct heated tube for high voltage regulation in shunt regulator configuration.
The DAC section and power supply section are in separate chassis.

Power Section
Power Input: 110V/220V 50/60 hz (factory pre-configured)
Output Capacitors: OIMP Oil Impregnated Metalized Polypropylene Audio V-Capacitors

 

Don't forget Metrum acoustics they are making there own chips

I think maybe you mean discrete circuits, because chips are for the big boy manufacturers to make Analogue Devices, Burr Brown, AKM, ESS ect.

Cheers George

I picked up a Denafrips Ares after my USB-only Wavelength Brick was no longer enough for the TV and other devices that I wanted the best sound quality possible out of. I've been burning it in fully before trying any comparisons, but locally some guys have Yggys, a Holo Audio Spring Lvl 3, and some other DACs. Unlike the higher-end Denafrips DACs, the Ares does not have a non-oversampling mode (I mistakenly thought it did when I purchased it, though now I'm not bothered).
At some point in the next month I'll try to get some organized comparisons of the DAC with others. I'm definitely enjoying it in my home system.
