Playback Designs MPS-5 - Measerments v. Sound


For all who are curios to read Michael Fremer`s comment
on one of the most controversial reviews in Stereophile (Feb 2010) concerning PD MPS-5 cd player, in which the ultimate question rises again - Can we actually measure perceived sound ?

"Thanks for writing. I would appreciate it if you'd post my response on Audiogon.

It's interesting that you say "it's time to rethink measurement methods" because John Atkinson just took the player back with him to perform some new ones on that player.

It's important to understand that the designer of that player has been at the forefront of DSD technology almost from its inception. Read the bio notes on the Playback website and/or in my review (which was written of course before I had any idea how the player would measure).

Andreas Koch knows what he is doing! That player's measurements are not the result of a botched effort or because he is unable to design a player that will measure as "perfectly" as is expected in conventional terms. Just as it's fairly easy these days to design a speaker that measures "flat" on-axis. But that is hardly the end all and be all of good speaker design!

Atkinson recently met up with Mr. Koch at an event and they had a long discussion about the measurements and that is why JA is revisiting them. The players measures as it does purposely according to Mr. Koch.

Believe me about one thing: you will not hear "noise" as such from that player!

You also understand that there are anti-SACD advocates out there who claim that SACD is not a high fidelity medium! Those include Dr. Stanley Lipschitz, in who I distrust all the time, but he's got the measurements to "prove" his case.

I can "prove" to you that LP playback measures way worse than CD playback but the listening is what counts to me. We don't measure everything. Our brains are far more sensitive than any measurement yet devised. Yes, we also can be fooled but we are also excellent receptors.

JA admitted to me that he's not quite sure what Mr. Koch was getting at in their discussion but that he's open to learning and understanding. JA understands that Mr. Koch is well aware of what he's doing in that design and perhaps one day we'll all understand what he's doing and why what he's done makes that player sound so good.

I suggest you listen to it. Or measure it. If you measure it you may reject it, but if you listen, you might find it's the player you want to own....

Changster, thanks for posting. I will be purchasing a MPD-5 (no interest in SACDs) very soon and it was nice to read your' informed thoughts. I have been going through a lot of DACS attempting to find a DAC that can do 24/192khz and at the very least come close in sound (but hopefully better) my John Wright modified Bidat.

A number of newer dacs have come and been slain... LOL!!! Hopefully the Playback will be victorious. I had great hopes for my MSB unit, but while it is very very refined I think I am looking for something a bit different.
"O.k., just made the jump and orderd PD MPS-5. Lets see what the fuss was all about. Measurements v. The truth of sound....."

Have you received the unit yet? If so, what do you think?
Thanks.
Has anyone received the new upgrade board. I think it is an upgrade power supply. I am still waiting for one from my dealer. I wonder how much of an improvement it might make?
I did the upgrade a few days ago, after about 6 month of using the MPS-5 player. Hearing the player the last couple of days after the upgrade I can say for sure – this upgrade is a must. I remember one reviewer who wrought that the player sounded to him a bit "confused" and "uncontrolled" in the bass region. I also heard that . Indeed, the sound was always impressive with bass foundation but the musical picture was, to my ears, sometimes unclear, a bit unfocused in a way that I couldn`t put my finger exactly on it, but made me at times bothered and a bit detached.
I can not say what was the change they did (I have no electrical understanding but I`ve noticed some resistors were changed to capacitors in one part of the power supply section). The company did not disclose why they did the change and how it will influence the sound. But the change is to my ears a real wonder. Everything came into place and bass definition was lifted to SOTA performance, no more undefined or uncontrolled bass, no more blurred picture, and when you get the parts right and in place you get a complete musical picture. Involvement factor is at best. I can now fully "trust" this player`s musical message and for my taste and ears it has more organic and realistic musical presentation than anything else I know including the EMM XSD1 . If you`ve appreciated the MPS-5 player before, I think now you will understand better why. That at least happened to me.
Can this upgrade be performed by the owner or does the unit have to be shipped back to the factory?
