Is it possible to transform the EMM CDSA SE?

You might be right, but it is a sad component that needs that much work to sound SOTA, if the CDSA did not my float my boat for any reason, I would choose the path of simply buying a component that did, without the time and effort you are describing that might or might not get me "there". Fortunately, I happy with the CDSA as is, with some minor vibration control stuff I did - though I'm not sure it really made much difference, but figured it couldn't hurt. As a general rule, it just shouldn't be that hard and prone to tweaking, all major issues should be handled by the manufacturer, and generally are - if they have any experience, which EMM most certainly does.

I'm getting great 3d sound out of my stock player without vibration control. I am using Kimber Cable into a Levinson Ref Pre into a Boulder amp. The sound has depth, width, height, and the timbre is stunning. It is transparent and has weight. It is more three dimensional than my vinyl which is a reference Goldmund with a Ven den Hul cartridge. I would start suspecting my other components as orchestra's are live when associated cabling and equipment is in place.

highfi, that is the way I hear it too.

With all due respect, if this were true there would have been no need for EMM to bring out the X upgrade and then the XDS1. Those who are not in the market for these expensive versions have 2 choices: leave the SE as is, or try to improve it. I chose the latter route and have had great success. The sound that now comes out my speakers does not even resemble the sound out of the box. It has been more than worth the money and the effort. With the added advantage that if I replace any components in future, the money I would have spent on trading and upgrading will not be lost through resale. The system improvements will be there for the next components.

Sabai,

I have an Oyaide non filtered iec replacing the filtered iec on the EMM. That did improve dynamics slightly. And of course power conditioning & cords help. But the generation after EMM products did not sound to my liking. Then this latest generation is reputed to be much better (from what I have heard in unfamiliar systems) and probably is. On a different note: the new EMMs use a discrete output stage which is an improvement we can not obtain via mods etc. The signature of the EMM is as much due to its output stage as to the D/A stage. If I remember correctly they are using op amps inside which from my experience usually have a little less than absolute resolution compared to op amps. Usually with an upside of extreme musicality. At this level the EMM changes is like changing phono cartridges. Different flavors.

The Prism Orpheus is a professional studio DAC which is excellent but a step down in the bass from the EMM.

The latest EMM has digital inputs which make it much more appealing but at the price you can have the CDSAse and a stand alone DAC so I went that way.
