Okay, I've spent the better part of the last couple days playing around with the Marantz 2238B / KLH 22's / Dynaco A-25's using my AMC CD8b and AR XA turntable.
I've been considering assembling in the computer room a 'vintage' rig so I've been doing a lot of comparing of the Dynaco's and the KLH's to see what I like better.
Let me preface this by saying that BOTH speakers are ultimately listenable and are worthy on thier own merits of being featured in thier own rig.
While the LOOK somewhat similar, the sound is totally different. The KLH from the midrange on down is just silky smooth. Bass rolls of nicely, very laid back smooth sound. The treble isn't as smooth. Hard to describe as it doesn't detract per se from the overall sound but it could be improved on. Overall, these are a VERY musical speaker and very fun to listen to. Props to Mr. Kloss for designing a speaker that, maybe not a 'purist' speaker in terms of flat response but is just a pleasure to listen to.
The A-25's are a horse of a different color. The treble on these is very clean, clear, accurate. In fact, you could say that about the entire frequency range. It may just be me or because or just because I'm comparing them to the KLH's but they seem to be almost a little forward sounding in the mid to higher frequencies. The bass is adequate although with a 10" woofer I expected more bass. The sound, overall, is very clean and dry, I expected the sound to be more like the KLH's or Boston Acoustics but instead is more in the vein of B&W, IMO.
On the whole, I'd give the edge to the A-25 and I think that I'll more than likely hang on to them for this rig. The KLH's aren't going anywhere just on principle and cool factor alone.
