does it logical to invest on expensive transport?

I definitly desagree with 4est. numbers are numbers, it is the conversion of those numbers that matters. Only since the improvement of conversion(dac) has the digital domain began to show it's potential. What is possable. Besides, if you download there is no need for a transport. I have down loaded several 96/24 recordings. They sound great. Are they better then every cd I have ripped, NO! But most. If you have a lot of sacd's I understand your intrest in a player. But if you have redbook, move on. You will not beat it. And, in the end, you will be much happier with your system. MY OPINION!

Yes, absolutely a really good trasnport will improve performance. Absolutely no question about it. Anybody who says that it won't hasn't ever heard a good transport vs. a average one.

Are hi-res digital files better than the CD? No, at best, they are the same as the CD from which they were/are copied.

Can a server based source compare to direct from CD? Yes, with a good DAC.

Should you buy a really good transport? Depends on what you see for your future. Server based systems are very convenient and done right with a very good DAC can be truly great.

Teajay makes a good point, if you have a large collection of CDs that you prize and have no plans to download, a high quality transport is mandatory for optimal redbook performance. It`s amazing just how good redbook can sound in a well thought out system, old fashioned? but still excellent sound without question.

the ps audio perfect wave transport retails for $3000 and should be considered. it plays hi rez and is versatile as to its digital outputs. listen first before buying.

i have been told that there are number available for sale used on audiogon.

Mrtennis, I have to bust your chops on that statement (good heartedly of course):

"i have been told that there are number available for sale used on audiogon."

what are you too lazy to actually read the listings on Agon and must rely on word-of-mouth as to what is listed for sale? After all, you are/were on the site when you posted.

Cheers though to you ;-)
