I owned one for about a year around 2001, and only sold it because I acquired a Wadia 9 (not Series 9!) at a great price. The 26 is a 32X oversampler and is basically the DAC section of the Wadia 16 player.
It has the typical Wadia sound - lots of spatial detail, great bass, and better treble than the Wadia X64.4 it replaced. I used it with a Wadia WT2000S transport. It's been a while since I listened to it, but I think it would still be competitive with current low to mid priced DACs, and it's certainly well built.
Try to listen to it in your system before buying, if possible.
