I'd say the review seems reasonable overall, and I WOULD call it a Negative. (It's actually very refreshing to see a negative review in the audio press.)
First off, if you like the sound of the FAB's, keep 'em. Everyone's ears are different - literally. This is something which is given very little attention. While listening, just hold your hands behind your ears, or move them around a bit - the frequency response and timbre of the music changes dramatically. And your ear canal is different than others, even more so. So the tonal balance of the FABs may be the eq that works for you naturally, and not for the reviewer.
I personally find some of the newer designs' tonal characteristics unlistenable, which many people (including 6Moons) rave about, i.e. Gallo Ref III's. Are they wrong? I dunno - all I know is what I like. And I couldn't care less what the self-proclaimed "experts" say.
As to the specifics, however:
- I didn't get a feeling that the reviewer had any personal beef with Fabian. But he did have some healthy skepticism - "I asked Jim in an email some basic questions about the crossover (type, slope, frequency compensation) but he stated that he is unwilling to reveal more specific information about the design due to -- unsuccessful so far -- efforts by a competitor to clone FAB designs." Gimme a break! This stuff could easily be measured and/or reverse engineered by a competitor willing to buy a pair. Is the FAB brand such a hot seller that a knockoff is going to make someone's business?
Overall, I think Marsh tried to be supportive where possible while stating firmly that he had some serious issues.
Now here I'll say a few things that the reviewer may have pulled some punches on:
On a technical note, I suspect that theoretically there is some reason for what Marsh hears. Matching a 10" paper cone to a metal (or any, really) tweeter, as an 80-2000 hz. mid-bass driver in a 3-way design is a very unusual choice - and to me, anyway, seems rather odd. Since there's already a 10" woofer in the rear, why not use a nice tight 8" (or even 6") for the important mids? The FAB borders on a Talon-like design, which is very difficult to pull off succesfully even using high-tech, specialized drivers.
And frankly, it appears to me that the rear-firing woofer is loaded into the same cabinet space as the 10" mid-bass? This makes no sense to me. Whatever's going on inside that cabinet, and the interaction of the two drivers' on each other would be a mess.
Frankly, to me, this speaker appears to be designed for an aesthetic "look" more than as an assault on new audio-highs.
The choice of the RS speaker wire and NAD cd doesn't bother me (too much) if this is a setup that the reviewer knows well and is happy with. I don't subscribe to the "megabucks is megabetter" hype, myself - ESPECIALLY when it comes to copper wire. Different CD players have different attributes, and I've heard cheap ones that I loved and ridiculously expensive ones that I hated. Most high end players are just assembled from stock parts, packaged into a pretty box. There are very few companies actually building transports and A/D converters. However, if I was a reviewer I would use more upscale equipment just to avoid having to protect myself from the Hype Police.
One fault I do find with the review, and 6Moons in general, is the dearth of objective measurement. Yeah, oscilloscopes don't define the "sound" of a component, but especially in the case of a negative review like th FABs it would provide some verification as to what the reviewer is actually hearing and where it might be coming from. A basic spectral analysis is not difficult or expensive to perform nowadays.
Overall, I think the review is probably indicative of a "problem" with the FABs as most people will hear them, and I give credit to Marsh and 6Moons for running it. But again, that doesn't mean there's something "wrong" with a listener who likes them. It could be just the right match for them.
