    Does anyone here use the newest version of this digital EQ? After using my BFD on my subwoofer, I am considering EQing the rest of my system with either this piece or its analog cousin, the Ultra Graph pro. The digital EQ is at Zzounds for $199 while the analog version is $149. This seems like great pricing, especially on the Ultra Curve, but the question is...how does it work and sound?

    Bill,
    I expect how pleased you would be with these budget equalizers depends largely on your expectations and the quality of your equipment.
    I personally don’t care for add-on, full-range digital EQs because they add an extra AD/DA conversion to the signal chain.
    On the other hand, the Ultra-Graph’s noise floor is too low for my taste (-92dBu). You probably wouldn’t want to apply much boost in the upper octaves – but then this is good advice for most any equalizer. However, the Ultra-Graph has good THD specs.
    I did a search of the Forum and came up with the following responses from Ultra-Curve users:

    I’ve only come across one Ultra-Graph user that I can remember. He liked it, but he was bi-amping and using it only for the low frequency amp/speakers (i.e., all frequencies below the tweeter’s operating range).

    Thanks Wayne. I had read all of these before, but I am under the impression (perhaps wrongly) that the 8024 has been updated this spring with better converters. My 1124 has EQ'd my SVS 16-46PCi to within +-1.5db of flat from 18hz to 100hz in my room. This is very impressive! (I used sine tones every 1db and had to use all 12 bands of parametric EQ, but the results were so good I was baffled at my luck!!!) It took me about 9 hrs of tweaking to arrive at this result, but it measures the same on both of my 1/3 octave test cd's as well.
    Because of my results, I was hoping the 8024 would be as impressive. I know about the quantization noise at higher frequencies and lower volumes, but I was hoping the newest version would handle this problem better.

    I use the Ultracurve on my rears, and before getting a TACT used it on my fronts (Wilson WATTs).

    IMHO, the improvements with it outweigh the slight negatives of the AD/DA conversion, provided it is set up properly.

    One thing to note is that the 1.2 firmware version has a problem with the Auto EQ and requires an EPROM upgrade, although this isn't too difficult apparently. I would check with Zzounds to make sure you get the latest.

    For $200 it is certainly worth a try.
