Esoteric K-03X vs Accuphase DP-720

Thanks for information! Now I’m using a Esoteric G-03X Master Clock with my old X-03SE CD Player, I wonder if the sound quality has any big improvement if I use my G-03X on a K-03X? This is because I heard K-03X’s internal clock is very good, even very near G-02 Master Clock. Some user said even they use the G-02 master clock on K-03X but can’t hear big difference. Is it correct?

Mm622 hi, do you listen to mainly Redbook cd's?

The reason I ask is that Redbook is PCM and to get "Bit Perfect" conversion the best way, is for it to converted using a Ladder Multibit dacs, which your Esoteric X-03 has, and the best ones at that the PCM1704's, which have been phased out recently because they are more than 10 x the price to manufacture than Delta Sigma dacs, and never to be seen again, only in discrete form with companies like MSB do with their $40K Diamond DAC V.

"ESOTERIC X-03 4 x PCM1704 – SM5847AF VRDS-NEO VMK-3.5-10 – SPU3162"

Sending a Redbook PCM digital signal to a Delta Sigma type dac ( which are in the Esoteric K-03X vs Accuphase DP-720 so they can do DSD and SACD) is taking a step backwards from what you already have for Redbook cd replay.

So saying this if you play mainly Redbook and have no interest in DSD or SACD. Stick with what you've got, which is one hell of a machine for Redbook CD replay.

I would kill to have your Esoteric X-03SE

Hi Georgelofi

Thanks a lot! Your information are very useful, I need to study and think about this. And yes, most of my CD are normal Redbook CD, I have very few SACD or HQCD. But since my Esoteric X-03SE is nearly 6 years old, I'm thinking to get a new machine. Also I think DSD is a trend, it will be more and more popular, that’s' why I'm interested in DP-720 and K-03X.

Think long and hard Mn62, once gone, that's it for the best Redbook you'll get. Here is a small excerpt from a review of it against it's more than double the price big bother separates, (PO5/DO5) that uses Delta Sigma based AKM 32-bit DSD/sacd converters.

A/B review:
"The most critical difference between both is their dynamic ability and sense of pace and rhythm. I concluded the review of the P05/D05 by saying that their only weakness was some raw energy left behind, a small lack of rhythm and speed. No such thing can be said about the X03SE"

This is exactly what I hear even from the latest Delta Sigma based dacs that can do DSD, when playing Redbook the R2R Multibit dacs (your unit)just has a jump factor and midrange body that Delta Sigma simply can't match on Redbook.

PS: from what I gather your X-03se can also do sacd/dsd which means it down converts to 24/96 of the PCM1704, you could feed it DSD files to it's digital input on the back.

Hi Mm622,
As some would kill for the X03SE dac, you can sell this off for a song and use the resulting profits for a new dac that you can audition at home before a purchase decision. System synergy is paramount, as always.
