Which Wadia??

Lev335 is referring to a DAC - you were asking about a transport, right?
It always depends on your personal taste. All the WADIAs are of incredible building perfection. I tend to think that the younger the transport is - and the 270 is in current production line - the more improved the unit is. WADIA always stepped forward in their quality - never backwards. But since the building quality is so good - why not go for an older transport of your taste and budget.
When it comes to the DAC, however, things get more taste related. F.e. I do not like the Levinson DAC's AT ALL. But since you were asking about a transport I guess your DAC is already sitting on its shelf waiting for digital food?

Yes....my dCS Purcell/Delius is waiting for a better digital source than my tweaked Rotel-971. So far, I've found 3200's for about $800, 20's for about $2000, and a 7 for about $3700. A new 270 will run quite a bit more.

While I agree that newer is usually better, I've heard that the 7, while in production almost a decade ago was perhaps the finest transport Wadia ever made...and remains a reference standard today.

Any opinions on whether it would sound $3K better than a 3200???

the 7 utilizes a teac transport while the newer transports utilize the pioneer transport the teac is far superior

I used a #20 for over 5 years, never had a desire to change the front end, although I did change elsewhere. Then I got curious about this SACD format, looked like the 777es had the same build quality as the Wadia so I sold the 20 and DAC and bought a Sony 777es SACD player. I know that I am going to get people telling me that the Sony's are as good a player as the Wadia players sonically but I beg to differ. Sold the Sony and am back using the Wadia products. I know you didn't ask for a personal history lesson so in short buy the latest Wadia transport or player that you can afford and enjoy.....

I own the dcs combo too and you can believe me that this combo is NOT very sensitive to transports.
Reason is a superior jitter processor.I tried several transports,all of them were ok.
What I want say is, when you go for the ultimate and you can afford it, ok, but the difference in sonics is not so huge you will expect.
I think the Wadia 3200 is a really good unit. Cheap 2 . hand and most people have no idea, what they sell....
When you want to go up, there is imho no danger with Wadia.
