FS: Sony 7700 with Empirical Audio level 1 & 2 mods and Jensen cap upgrade.
Excellent condition Sony 7700 with Empirical Audio level 1 & 2 mods and Jensen cap upgrade.
The mods were designed primarily (but not exclusively) to improve the digital/transport function of this player and reduce jitter. See details below for what Steve from Empirical Audio has to say about the mods: 'The Sony Transport mods consist of two basic Mods with Turbomod extensions: 1. Power supply component upgrades - similar to ModWright level2 2. Rewiring of the digital output circuitry as well as parts rearrangement and addition of Stillpoints EMI material in the right locations "The Mod I power supply mod reduces power supply induced noise and the jitter that results from this. Will improve the analog outs. "The Mod II digital mod increases the edge-rate on the digital and optical outputs and eliminates crosstalk and other noise, thereby significantly reducing the jitter in the SP/DIF signal. Mod II does not improve the analog outputs and assumes that the player will be used as a high-quality transport. The audible effect is that the image focus will improve and high-frequency content will be cleaner. For instance, bongos will sound more like live bongos and be distinct from other drums when used in conjunction with a high-quality DAC, such as the MSB or PT P-3A.' Total cost of Steve's mods was $625 + shipping (not counting the cost of the Sony). $525.00 obo + shipping. That's $100.00 less than the cost of the mods by Empirical Audio alone! Thanks for looking!
