I listened to a pair of Harbeth super HL5 plus tonight and I think these may take my Thiels' spots. Definitely a non-fatiguing sound, with the best ability to separate individual instruments of my listening so far. Also the best chamber music and jazz trio presentation, with a palpable sense of the players in the room. I've heard better renditions of the Tympani shots in Sibelius 1/Scherzo, but i could pick out the instruments, hear the wood in the strings, and feel the venue. I discovered some new information in each of my audition tracks. And, important for us apartment dwellers, they still drew me in at low volumes For those interested, the other equipment was Aurender-Backert Rhumba-Bryston 4B cubed. |
@ronkent, I've posted much of this before on this thread, but here it is again: https://www.stereophile.com/content/thiel-cs24-loudspeaker-measurements Notice that the Thiel CS 2.4's spend the vast majority of their time "..significantly below 4 Ohms between 100 Hz and 50Khz.." with a challenging phase angle to boot. https://www.psaudio.com/products/bhk-signature-amplifier/#tab-specs Notice that PS Audio only indicates that at 2 Ohms the BHK 250 is only "Stable for musical transients". That's a rather low bar for these speakers, basically saying that the amp won't blow up if briefly exposed to 2 Ohm loads. No mention of how much power and for how long it can deliver that power into that load. Well, never mind "...musical transients" we can see from above that the Theil CS 2.4's practically live in that impedance region. Now the BHK 300 seem to be spec'd much more up to the task, though the amps are not quite doubling down to 2 Ohms. So one is paying for some unused power over the vast majority of the time. Still this would appear to be a pretty good match. Notice the last sentence: "....,though it will perform best with speakers having and impedance of 4 Ohms and above.-John Atkinson I have no doubt that these are fine amplifiers, and that they can provide much enjoyment, but at nearly $15K I think one could find amplification better suited to the demands of speakers like the Thiel CS 2.4's I don't mean to pick on PS audio (FWIW, I'm quite impressed with their digital products, though they are rather expensive), similar results can be found on many of the other highly touted amplifiers. |
Meanwhile, back in 3.5 land.... So I collected the components from the parted out 3.5 from our Long Island friend (thanks again, btw!) and I'm ready to ship the mids to Rob for a rebuild. So my question (TomThiel), would there be any value to redirecting the rebuilt mids (Scanspeak 13M/8351) to you or someone who could map the frequency curve to compare with published frequency curves of the two most popular Scanspeak replacements? The idea is to find the closest (understanding that it won't be a perfect match) to the original for those 3.5 owners that may have received a pair of 3.5s where the original mids have long departed (which was the situation I was in). Also included in my haul were the original crossovers, tweets and woofers. I'm hoping to help out the community a bit here, let me know what I can do. |
