Looks like the waiting list may be infinite, though...

    For $700 I would gravitate toward other options instead. Better quality source, upgraded speaker cables/ICs, etc.

    You guys are forgetting that Chief Tonologist, Alberto, is personally calibrating each and every one, and including an inspected by Alberto signed certificate of calibration greatness.

    That alone has to be worth something to autograph collectors.

    700 for a variable bass enhancement . I don't know. :/

    hrm let me put on my builder hat...I box...I can make that, a circular object, yep can make that. Make the two connect to each other and make the circular object spin, CHECK! Install a interconnect with female ends inside the box and make it look pretty yet do diddly squat...easy and I can charge a million bucks for it! I"ll make sure to add 500% placebo effect!

    I got one when he was just coming out with them on AA back in.... I think 2014 . It is 100% passive and it does a good job. Alberto is a nice guy as well as a huge sound / music fan and on several audio boards.

    This doesn't work like a typical loudness button. It is quite different and it did work without adding anything artificial sounding. It did help take out some harshness from poor recordings without sounding fake.

    That's cool to know.
    In all seriousness, the description implies (well -- I infer from it, more to the point) that the gizmo is a more sophisticated (albeit passive) network than the usual Fletcher-Munson style loudness compensation. Wonder if there's some aural crosstalk "tuning" going on with it, too? ;)

    Seems to me it would be straightforward to feed signals into it and suss out what it does to them (at least in the sense of amplitude vs. frequency given input frequencies at fixed amplitudes).

    For crosstalk thingy -- feed some signal into one channel and look for some signal in the other one! :)

    I'm just spitballin' here -- for all I know there may be reports out there on how it works (I haven't looked). I just found the ad copy on the site to be quite amusing. It is too bad that the lower-cost version hinted at on the site apparently never saw the light of day.

    Tone controls seem to be makin' some sort of trendy, hipster comeback.

    From Bruce Rozenblit's Transcendent Sound newsletter, received yesterday:
    New Product: The Fixer is Here!

    This is something completely unlike anything in the lineup. It is a unity gain line stage that has volume, balance bass and treble. That's right, tone controls. The purpose of the fixer is to correct for deficiencies that exist in many systems. Most rooms are not perfectly acoustically balanced. Many times, you don't want to sit in the middle of the room. With the balance control, a proper acoustic center can be obtained.

    Many recordings are too hot in the treble or have too much bass. Some speakers need just a bit of bottom end punch. The Fixer gives you the ability to correct these problems too. Now I tried many different configurations of tone controls and they all garbaged up the sound. This design does not affect the sound when the controls are at 12 o:clock. The tone section is an active all tube design. The controls can be adjusted to gently change how your system sounds. They don't hammer it. The bass begins operate at 300 Hz, rises to a maximum boost/cut at 50 Hz and then levels off. The treble begins at 2000 Hz and rises to a maximum boost /cut at 10,000 Hz. They are essentially shelving controls. The maximum boost/cut is +/- 10 dB.

    The Fixer is dead quiet. The bandwidth is flat from 15 Hz to 400 kHz. That was not a typo. It goes out that far. All the clarity of the music is preserved. The sound is close to The Masterpiece in quality. It's not the same, but it is not intended to be. The Fixer serves a different function. It corrects for problems. The Masterpiece is best sound possible, and it drives headphones. The Fixer can be added to any system since it has unity gain. The kit price will be between $500 and $600 with tubes. It uses one 12AU7, one 12AX7 and one ECC99.

    I'm more of a two knob kind of guy. I like symmetry. Something for both hands to do.

    I think it was 200 on the AA test group. I haven't been on AA in a bit but I will try to pull up the thread.

    Alberto had a bit of info on how it was designed and use on video and a thread somewhere. It's been like 4 years so I'm trying to remember.
