To Hans Wetzel,

[I] really enjoyed your KEF R900 review -- thanks.

I am planning to purchase a Hegel integrated product -- not sure which one just yet. I was considering KEF’s LS50 or R500 [to partner with it]. Funny you mentioned that you listened to both of these for about ten minutes and that was enough. Was it just the bass and scale that didn’t do it for you versus the R900?

I would respect your opinion on the KEF LS50 versus the R500. I plan to audition what I can but stores are few near me.

When I first considered KEF’s R-series speakers, it was always going to be the R900. I wanted a floorstanding loudspeaker with bass that was as full-range as I could get. My brief listening session to the LS50 and R500 was simply to confirm what every other reviewer up to that point had said about KEF’s Uni-Q driver unit -- it was, and is, pretty spectacular.

Since I wrote that review, I wound up moving from the R900 to the Definitive Technology Mythos ST-L, which Roger Kanno reviewed last year. Rest assured, that move was purely lateral in nature, as I happened to prefer the DefTech’s powered bass section and svelte, Dark Knight-esque profile. At the same time, I bought a pair of LS50s that I will hopefully keep forever, so I’m staying in the family.

The LS50's Uni-Q is slightly different than the Uni-Q found in the R-series speakers (short of the R100 and R800ds), as it is a two-way bookshelf that is not supplemented by one or more woofers. As a result, it has a slightly different character, with just a touch of midrange bloom compared to the R500’s airier presentation. The bookshelf also benefits from a cabinet that isn’t just a folded box like the R500’s. If you're not dying for deep bass, and/or you have a smaller listening space, the LS50 is truly a steal at $1500/pair. But if you plan on pushing whatever you buy to high SPLs, the R500 is your best bet. Its three-way arrangement, combined with far more cabinet volume than the LS50, will make for the more dynamic loudspeaker.

As for the potential Hegel purchase, the H80 integrated amplifier-DAC is very good and will be a great match for either of the speakers you mention, but the H160 is the sweetheart of their range. Expect to see my review of it in the next month on SoundStage! Access. . . . Hans Wetzel
