Enjoy SACD sound quality
from your existing Red Book CD library.

Yes, you heard right.  It's time to get all the musical satisfaction you've been missing from your current CD library.  It's been there all along and our unique vacuum tube circuitry will finally deliver all the great musical performances that standard CD's can give.  A piano will sound more like a piano from the first octave to the eighth.  The strings will vibrate cleaner and echo more naturally.  The upper octaves will sing smoother and with less grain.  Solo vocalists will seem more present with richer fuller voices.  Drums and other percussion instruments will be delivered with more power and authority.  Horns and trumpets will sound more like brass than aluminum. 

If you're searching for a smoother more analog sounding performance from your standard CD's, you've just found it.  Our Model #657 Tube CD Player exceeds even SACD performance at  sounding more like analog vinyl.  There's no need to change formats or replace the library that's taken so many years to build.  Simply upgrade your existing library to better-than-SACD sound quality with a Granite Audio tube CD player.

With the extra power output of the tube section and separate volume control, the Model #657 can power virtually any power amp directly, without the need for a preamp.  It will even drive SET power amps with low input sensitivity.  This is an ideal CD player for music lovers who only use CD's for their music source.
There are a number of excellent
upgrades and modifications now available for the Model 650 and 657 Tube CD Players.

PCM1710U   Stereo Audio

20-bit  INPUT RESOLUTION

PCM1710 is capable of accepting either 16-bit or 20-bit input data.  Some improvements in dynamic performance can be realized by using 20-bit data.  When 20 bits are used, dynamic performance is improved by approximately 2dB. Refer to "Typical Performance Curves" for a comparison of 16-bit and 20-bit data.  Internally, the PCM1710's digital filter uses only 20-bit data. If the input data is 16-bit, the filter adds four zeros to complete the 20-bit input word.


ADDITIONAL  FEATURES

COMPLETE STEREO DAC:  8X Oversampling Digital Filter,  Multi-Level Delta-Sigma DAC,  Analog Low Pass Filter,  Output Amplifier.
HIGH PERFORMANCE:  -92dB THD+N,  98dB Dynamic Range,  110dB SNR.

DESCRIPTION

The PCM1710 is a complete stereo audio digital-to-analog converter, including digital interpolation filter, delta-sigma DAC, and analog voltage output. PCM1710 can accept either 16-bit normal or 20-Bit normal input data (MSB first, right justified), or 16-bit IIS data (32-bits per word, continuous clock). The digital filter performs an 8X interpolation function, as well as special functions such as soft mute, digital attenuation, de-emphasis and double-speed dubbing. Performance of the digital feature is excellent, featuring -62dB stop band attenuation and 0.008dB ripple in the pass band. PCM1710 is suitable for a wide variety of consumer applications where good performance is required.
