Newbie question - model naming conventions

[mdconnelly]

Hello forum members!

Greetings from Singapore. Long time reader - first time poster! Really enjoy reading the perspectives and appreciate the expertise of the forum members here!

I've been contemplating for a while now to upgrade to a Devialet deck but am a little confused about some of the model names. Specifically, I can see that there is a current Expert Pro line which includes a 130, 220 and dual mono configurations. I have also seen a 250 Pro in some literature also. Are there material differences (outside of output) of the 220 and 250 Pro models? Reason I ask is I can find some 250 Pro models used for a fraction of the price of a new 220 Pro model here in Singapore.

Any advice is gratefully received!

Check that it's definitely a 250 Pro, and not a 250..... if it is, and you like how it sounds, go for it!

I agree.  The used market can be risky in terms of product naming.   

Current product line: D130 Pro, D220 Pro, D440 Pro, D250 Pro, D1000 Pro

I saw a "Devialet Expert 200 Pro" advertised on Audiogon.   When probed, it was clear that it was the older 200 and not a "Pro".
