@thoft There's no way your going to drive 7.2s properly with this Adcom, you need to find Krell FPB 400CX for 7.2s.You'd better look for 3.7s much easier do find, best amp for this model is by far Gryphon Diablo 300.I might buy a pair of Thiels for the fourth time but i still need to think about it.

My audire forte can do 2 ohms 400 watts but problem is that the parts for the amp is so rare I don’t want something to go wrong and then it might as well be paperweight. Anyone got recommendations for amps I can find used under 10k for the 3.7 cause I’m probably more likely to get the amp first than the speakers. |
@thoft, Hold on. You might not actually prefer these to the 3.5’s. The 3.5’s will actually play deeper in the bass and do so with greater cohesion. The 3.7’s are better at dealing with the lobbing issues, both are more dynamic, especially the 7.2’s. The cost of amplification will certainly go up with either. On the other hand, replacement parts are much more available than are for the 3.5s. The BHK 250’s : https://www.psaudio.com/products/bhk-signature-amplifier/#tab-specs aren’t rated into 2 Ohms, being " 2 Ohm ....stable into musical transients" only suggests that the amp won’t go into oscillation when temporarily confronted with such a load. Same for the M700’s: https://www.psaudio.com/products/stellar-m700-power-amplifier/#tab-specs Class D amps are not typically comfortable with sub 4 Ohm loads, The BHK 300’s seem up to the task, but not especially enjoying it: https://www.stereophile.com/content/ps-audio-bhk-signature-300-monoblock-power-amplifier-measurement... These later Thiel’s don’t just visit these lower impedances; they live there: https://www.stereophile.com/content/thiel-cs72-loudspeaker-measurements https://www.stereophile.com/content/thiel-cs37-loudspeaker-measurements @Thieliste has given excellent advice recommending some of the best amps for these speakers. The Momentum amps jump to mind as well. The Gryphon’s are probably the best amps I’ve ever heard, but the are not inexpensive(!), and the US distribution has been inconsistent in the past, new ownership seemingly following the originators design philosophy might change that, but the possibility of having to ship these heavy amps back to Denmark is a bit daunting to me. The Krells seem to need to be recapped a bit more often than some others and that’s not cheap either, though IMHO worth it. The Luxman specs are somewhat ambiguous. |
