CD player how much to invest


I sometimes wonder should I invest more in digital playback in the future. My current CD transport is a CEC TL51x with a Wadia 12 DAC.
From shows and visits to friends I have learned that there are better CD players out there then my combo, but at what price. The AMR CD-777, is a little better but at €4000 twice the cost. The AMR CD-77 and Nagra CDP are even better still but they cost 10 times or more then my combo.

But is it worth the investment even if I had the money. I believe that with say €2000 you can buy a good CD player That is maybe 90% of a €10.000 CD player.

However I do think that speakers and turntables have a higher return on investment sonic wise. A friend of mine will bring his Jadi Symphonia with Electraglide powercord + Harmonic Tech Magic Link I interlink. To compare. I somehow doubt it will be much better, it may be different but better I don't know.

I am wrong to think that? Are more expesive CD player really a lot better then mid priced and if so how come?

Sorry for my rant, but when I was thinking about upgrading my set and maybe buy an other CD player would it be worth the money? Will I hear a difference etc.

Ironically, the only other forums that I've participated on that have less concensus are religious forums. It amazes me how similar the discussions in audio and religion really are. The biggest difference is that there isn't a judgement day where we will find out who's audio system is really the best.
Mordante;

1."But is it worth the investment"-Only you can decide;In my case it was a firm Yes.

2. "That is maybe 90% of a €10.000 CD player"-.true.BUT,isn't in true for everything else too?

3."Are more expesive CD player really a lot better then mid priced "..OF COURSE!!!!Without a shadow of a doubt!!Of course the rest of your equipments must be up to it too

4."if so how come?"many reasons,mainly better power supply,better parts,better brains designing them ,etc...

I think you should really put dcs Puccini ,Neodio,and Wadia in your list .
"However I do think that speakers and turntables have a higher return on investment sonic "-I beg to differ.I think the law of diminishing return is true for almost alll the equipments,especially loudspeakers..

"I somehow doubt it will be much better, it may be different but better I don't know."-The same is ESPECIALLY true for loudspeakers too
For about $12k you can buy a Nagra CDT. The Boulder 1021 is about €24k I have heard them both at a dealer show. Now to be honest I don't think the Boulder is a lot better. Not even sure if it is better at all. So the difference is about $12K. That difference will buy a set of Sonus Faber Amati instead of the Guarneri, etc. The difference between $12k and $24K speakers is IHMO a lot bigger bigger then $12k CD player and a $24K CD player. I think at a certain price point audio doesn't get much better just a different taste.
"I don't think the Boulder is a lot better"-you are right,but Try the Nagra CDT vsPuccini?Now there's something else.Likewise a Puccini vs Scarllati stack....the differences are not subtle.Actually I have found out that very few manufacturers know how to make digital gears well,If youn stick with the well known digital specialists I think you are OK.It si easier,WAY>>>>easier to get a well made speakers than well made digital gears

BTW,I personally prefer The Nagra to Boulder 1020,even though it is cheaper.
