Sony SCD-XA5400ES-Best SACD for under $10,000

A great power cord CAN make improvements, but to what extent they effect ones perception of the sound is as unpredictable as the individual using it. An MIT power cord will address many aspects of powerline contamination, which will allow the component to deliver vastly superior performance in real world terms, such as better dynamics and dynamic contrasts, superior low level resolution and reduced distortion. Imaging and tonal accuracy are often discernible as well. Of course you don't have to believe ME...just arrange for an in home demo from Joe Abrams at Equus Audio online.

I also own the Playback Design as well as the MW 5400. I have Dan's additional mods, Nichicon Caps, Bybees, Audio Magic pulse generator as well as the latest
umbilical cord. This adds about $1300. to the 2K standard mod. I've also upgraded the tubes with a Mullard rectifier and NOS Tungsol 6NS7s (I preferred these to Sylvanias), as well as after-market power cords. I have an after-market power cord on the PD as well. The MW is very good, extremely musical....the addition of Dan's umbilical cord was a surprisingly big improvement....more dynamics and vibrancy. However the PD just exceeds it in just about every way....the best digital I've ever heard and I've owned and heard quite a few of the "best". However the PD DEFINITELY needs 500 hours of burn-in. Read Fremer's review in Stereophile....a most unusual change in sonics during those 500 hours. I went through almost an identical series of sonic upheavals during that process....which actually made me doubt my ears!

Lula, JWM and I have made the same exact "upgrades" to our MW's as you; Audio Magic, new umbilical, NOS Mullard and Tungsols(black glass) and each change made for serious sonic improvements and were all worthwhile. That said, the "stock" MW still sounds fantastic.

You may well be right about the additional break-in time needed for the PD. It really does sound pretty ordinary at the moment but JWM has it running 24/7 and we're waiting to hear what happens. One of us will no doubt report back.

Dave_b, if your MIT power cord made a significant sonic improvement, that's great but in my experience and the experience of four 'phile friends who own very expensive systems, we're all in agreement, the sonic changes made by power cords are subtle at best and often not for the better.

All but one of us have dedicated 20amp lines powering our equipment. I have four; one for each mono amp, one for digital source and one for analog source. We've all tried various cords, some quite expensive, and often, we try them in each others systems. As I said, the consensus is, the changes are subtle at best.

My suggestion to anyone considering a power cord change, upgrade your power first. What I find interesting in your case, you spent more on your MIT power cord than on most of your other components. Some might find that odd.

an inexpensive mod, i have been told by a tech, is to replace the cheap op amps in the sony.

i wonder what improvement will result, in absence of other mods ?

Rfogel8, I've owned $4k power cords and $20K plus wires with many 6 figure systems over many years....my meager AC 1 has been around for years and the system I speak of is for my smallish sitting room. I did mention that what one hears is dependant on the individual, in other words, not everyone listens for the same things. Some aren't able to or simply don't put a priority on low level resolution or micro dynamic contrast...hell some wouldn't know the sound of a violin from a viola. Small improvements in a reference system are HUGE for the audiophile anyway! I've been to so called audiophile parties where the volume level barely reached that of a small am radio at 20 paces, and there was more hum in the system then musical content. Habits and priorities will determine alot of what is decided during ones evaluation of a given product.
