Bill exemplifies a dying breed - someone who knows musical technologies with fluency coupled to the requirements of the musical arts. He will be missed, and I don't know if he'll be replaced.
Bill has had the Thiel CS3 / 3.5 equalizer in his backlog, but alas, has run out of time to address it. But he did do his last Oppo 105 Music Technologies upgrade for me. It is wonderful and serves as my CD and SACD source at considerably higher level than either the stock Sony 9000ES or SCD-1 from Thiel Audio's sale.
I had met Bill in the way-back days when he was the manufacturing director of Conrad Johnson in their first two decades. But we lost touch on my hiatus from audio land. I really appreciate you recommending him to me; we have had a few years of enjoyable, productive interactions. I wish it could go on - All things must pass.
I highly recommend anything with Bill's signature on it.
