I am listening tonight to my Senn HD650 with Ted's silver balanced cable, out of a Bryston BHA-1 amp, with BDP-1 digital player and FLAC files ripped from CDs, along with the Bryston BDA-1 DAC feeding bal analog output to the BHA-1.
Here is the 650 with silver cable: (shown with my other reference, an LCD-2.2)
Albums I am enjoying tonight:
Bought this silver OCC cable back in late March, and have used it extensively on the 650. On the Schubert Quintet's sublime adagio, the strings shimmer with a celestial sparkle that the stock cable came nowhere near replicating. The cello did not lose any of its warmth, and imaging was pristine -- I could almost reach out and touch the 5 players. On Grimaud's virtuosic rendition of Beethoven's dynamic "Emperor" concerto, her piano key strikes sounded more realistic, and orchestral strings were better textured in the sublime slow movement. In the first movement, a real test for dynamics of any headphone system, the silver cable gave my 650 smoother, brisker attacks in the brass crescendos. Piano rarely sounded more realistic with the 650s paired with Ted's cable. Yummy to say the least. The only limitation, if you can call it that, was that the soundstage did not widen with this cable. The 650s are known to be a very intimate HP, putting the listener near the front of the stage. The silver cable did not change this fundamental character, which is good. The last thing I needed was to have the cable turn my beloved 650 into a baby Grado.
Finally, one of my fav albums -- Pat Barber's Companion. On "Like JT", the warmth of the bass appeared like dollops of luscious butter hanging in mid-air. The silver cable made the twang of the bass strings a bit more audible, and softened the reverberations a tad bit. The percussion cadenza of "Black Magic Woman" sounded tight, with the shimmer of the drum kit more forward than with the stock cable. Barber's voice on all tracks of this album was clearer, more lifelike, and a tad leaner, almost as if she had been through a Jennie Craig program! In contrast, the stock cable made her seem more "rounded", fuller, almost chubbier. Not a huge difference, but a noticeable one.
Overall, I would highly recommend Ted's silver OCC cable for the 650, especially in balanced mode. In SE mode, with a Cardas HP cable, the SQ was fuller, warmer, and less detailed up top. Still pleasant nonetheless. But if you crave those upper-mids like I do, especially for classical music, then Ted's silver is the way to go for the 650. Much has been written about the "veil" of the 650s. I did not find the 650 to be "veiled". Their highs are just not in-your-face. The silver OCC from Ted did not change the relaxed character of the 650s, but they did give them more "air" and better rhythmic spice than the stock cable.
