I have a mint condition Sony Playstation 1 Model SCPH-1001. This is the Playstation 1 model that has received great reviews in both Six Moons and Stereophile.For an additional $45, I can also modify the output stage and upgrade the capacitors in the power supply. These mods work well together to improve the sound. - Deeper, extended and more detailed bass. - Extended high frequencies. The sound is no longer rolled off at both frequency extremes as some have claimed with the stock Playstation. There is greater air in the presentation and the recording venue acoustics are better conveyed with improved detail and extension of high frequencies. - Higher level of detail while retaining the midrange warmth of the stock unit (this is really evident once the output stage capacitors have had some time to burn-in). - Larger, more expansive soundstage in all three dimensions. - Improved imaging. I believe that with greater detail, the space around the performers is better defined. You can read about other tweaks on the Audiogon discussion thread where I have posted some of my findings. The best way I can describe the result of the mods is that it addresses the weaknesses of the stock unit and retains all the sonic virtues of the stock unit. I was careful not to completely change the sound of the Playstation. Please note that the audio output will only come through the RCA audio jacks, and not through the AV Multi-Out port after the output stage modification is performed. The caps on the power supply should be changed anyway, since most electrolytic caps have only a 15 year lifespan. Most of the Model SCPH-1001 units were sold about 10-15 years ago, so the caps are about to expire. For assurance, you can view my Audiogon rating under "rhing," and my eBay rating under "richard_hing."
