Both my Wadia units, the 64.4 DAC and the WT2000 transport are over 15 years old. Never had a problem. The transport was upgraded about 13 years ago and received the heavy duty Teac mechanism (S mod) similar to the VDRS used by Esoteric in their current $13K models.
I recently sent the transport to Steve Huntley at Great Northern Sound to get a cleaning, lube and check-up. But that's all.
Wadia was a different company then, and I don't have any experience with their new products. But I will say this: the 270se does use the very best VRDS 3.2 mechanism from TEAC/Esoteric. But it's just a transport, so you'll still need a DAC. The 781i is a complete player, but so far, Wadia literature doesn't say just what transport mechanism it uses. You might want to call them. If it isn't a VDRS 3.2 by TEAC, I'd pass.
