I dont think you can beat the sacdmods 555es in the $1200 category for sacd or cd playback. How it compares to other more expensive digital is hard to quantify. I had a fully tricked out Perpetual Technolgies p1a digital upsampler-resolution enhancer and p3a 24/96 dac combination. This included the upgraded Monolithic Sound power supply, upgraded Revelation Audio I2S cable and an upgraded Audioquest ac15 power cord for the power supply; and upgraded Revelation Audio power cords for the p1a/p3a. This Perpetual combo is rated stereophile class A . The Perpetual units were driven by a dedicated PS Audio Lambda cd transport rated stereophile class B. Furthermore, the Perpetual units were fed by a PS Audio P300 power regenerator.
When I compared the two, the sacdmods 555es was plainly better to me. This was with cd's, let alone sacd's. I dont know if the Perpetual units are overated because they sound exceptionally good, however, the 555es had all the strengths of the p1a/p3a along with better bass, dynamics and especially a fuller, more complete tonality. I didnt keep the Perpetual units more than a couple weeks after that before I sold them. I enjoyed the Perpetual combo immensely before I heard the sacdmods 555es, but the sacdmods player just overwhelmed me. Those Perpetual units with the upgrades cost me over $2200. The cd transport was $2000 new. The sacdmods player cost me just under $1200. How can you beat the value and performance of these modded 555es players when you look at this comparison?
I also auditioned a Sony XA 777ES ($3000 retail/ $2000 Oade Brothers best price) on better equipment, in a very good sounding room and I didnt think the sound was as good as my sacdmods based setup. The 555es had more life and more refinement. I could see the sacdmods 555es competing with very good $3000 players step for step.
I also want to mention the sacdmods 963sa. This player is extremely good and rivals the sacdmods 555es for about 2/3rds the price. I dont see what is going to compete with this player at that price point. Again, where this player falls in the pecking order is hard to establish but it has to be one of the top options in the $600-1200 price range. The regular 963sa is mediocre from my auditions, but once its modded with a zap filter output stage; it is transformed. Unfortunately, I am the only one who currently has one of the modded 963sa's so I am the only one who can currently comment. In the meanwhile, if you cant find a 555es, and feel you can trust my comparisons and conclusions, the 963sa is a splendid alternative. Gradofan is supposed to be coming down to hear my setup soon, and he owns a stock 963sa, so hopefully you can hear an informed second opinion as to the quality of the sacdmods 963sa over the stock unit.
