I'm with you on the sibilance and cold top end of the WFS DAC-2. When I returned it to the manufacturer citing my experience, they swore up and down that no way could that be the case, must be something up with my system.
That makes me laugh, it really does. Every single person I have demonstrated my WFS to noticed exactly the same thing. Just Saturday last week I had a guy over to check out the John Kenny Saber DAC and we compared it to the WFS - basically it was un-listenable compared to the other DAC's including the JK Saber.
I believe it is the exact opposite - people who don't hear it have suspect systems. The speakers I was using, ML3 Reference (they are lined with steel and use hellishly expensive VSF Copper Capacitors that just by themselves have a wholesale value of $3.5K) are the bigger brothers of ML1's that totally wowed an audio club meeting in NY to hear the new Bryston amps:
'The ML-1s sounded wonderfull in every way. Giant killers ? From 50 hz up yes indeed. Even though the ribbons of the Carvers were still connected. When we noticed some upper midrange and lower treble excess energy Mark actually made the discovery. When corrected these little babies stunned us with their tone. Lacking in the low frequencies the bass at 50Hz was spot on in every way.'
'Not much to add onto what others said re the Lenehans - Clear, clean, pure, open, yet for me absolutely subwoofer is a must. Gorgeous cabinetry on the outside and very heavy for their size. A very revealing speaker that in the right hands will sound otherworldly good, but also has the potential to be too revealing of a bad source. I would not want to listen to bad cd through bad SS gear. It's a small tribute to the Digital Amp Co Cherry JR that even though it's a Class D amp, the Lenehans sounded glorious with it, when the right source (EE DAC but to a greater extent Carl's DAC) and pre (Carl again - see a pattern here?).'
They allow you to only too readily hear the problems with a DAC like the WFS. I really would like to know what speakers WFS use just so I can stay clear of them. Just kidding - but seriously though it does leave me scratching my head about the equipment they use.
Thanks
