Weltfaul

I resuscitate an old thread, but in the light of all the opinions what conclusions are to be drawn from Klipsch's own suggestion of 100W minimum for the Heresys?

I 'solved' this problem using this: I only need 6 ft per side, so I join two opposite colors at the amp end and connect all four at the speaker's bi-wire end. It's solid core OFC copper for special electrical installments; no complains whatsoever about the sound and I don't have to mentally fiddle with jumpers anymore. €30 5 mt. shipped from Germany.

In my case, it's a very weird opposite... My wife never discourages me from audio experiments, it's me having all sorts of reasons for not buying.

Thanks, if my H3s had an impedance pattern as the 1s, they would be a great match with valve amps. Nothing below 10 Ohms is as rare today as a loudness control...

@jcn3 I am not sure that the two cabinets sounded different; it would have been a very long shot to assume I had aural memory of one noise of months and months before. Let's say that I knocked on the second pair, I had a certain feeling of hollowness and wondered if the first pair also sounded that way - since I am sure I had knocked on them too. But I also think that having bought a second pair because I had sold the first one, and feeling a little silly about it, I had more expectations from this new purchase, and was more ill at ease about any possible flaw in the speakers... When I had my first pair and a PrimaLuna EVO 100, which is rated at 42 watts/8ohm, a guy came by to hear them, bringing some CDs along; he played loud electronic music and the Heresys produced deep, sonorous and non resonating bass; I suspect that my otherwise honest TEAC amp is not controlling the 12" woofer as it should. BTW, has anybody seen a graph for the Heresy IIIs' impedance anywhere? The only review discussing their impedance is that by Dick Olsher on The Absolute Sound, which essentially says that they can be considered 8 Ohm speakers. I don't care much about it safe that tube amps must be chosen considering the impedance/phase pattern of the speakers too. Thanks to all M.

@jcn3 Thanks, this possibly answers my question about damping material. As for power, I am aware of the infinite variety of amp responses to drivers and crossovers.. I have somehow given up finding the ideal pairing; having tried a PrimaLuna already with good results, I may end up with one again. @Joe Carter, I think that my 3s' crossover is a dual-layered PCB fixed to the inside of the binding posts' pit. Suffice it for me that everyone else's Heresys behave more or less like mine.. @001, Who said I can't..? 🙂 M.

Hi, thanks. I sort of thought as much, basing on my previous experience - the Pass, the PL. It's probably something with the TEAC amp. I'm still amazed at how someone claims that the H3s' woofer is ok with a 5W tube amp, and others that it takes lots of solid state watts... I guess in the end it's all down to getting lucky with the right amp and to personal preferences, letting objective science alone.. 🤫 M

Thanks. The recordings may surely account for some resonating bass, but I hardly think that they may be the culprit of some hollow sounding knocks.. Speaking of recordings, they are absurdly variable in quality; also, keeping the speakers close to the ground doesn't sometimes help with transparency and clarity. I don't remember having ever heard boomy bass with the PrimaLuna, so I might as well check the TEAC's true capacities. M.

Thanks anyway. I'm still asking somebody if the Heresy IIIs have damping stuff inside. I have not, and will never, open my pair. M.

Yes they are, and yes they were. Thanks.

Hello, I now have my second pair of Heresy IIIs - I stupidly sold the first one - bought last year, Spring 2021. Since I bought them I have a weird feeling that this second set, when knocking on top or sides, sounds more 'hollow' than the first pair, which was scarcely two years older. Also, the bass in some recordings seems a little less controlled and a little 'boomy'. It could be the amp - was a PrimaLuna EVO 100 and now is a TEAC A-H500i - but the feeling of a certain 'emptiness' from the sealed boxes is still present. Does anybody know if there is any absorbent inside? I now keep my IIIs on their slanted bases. Thanks for opinions, suggestions or plain reassurances. Max

@Fido: Glad to have been helpful. Max

@ the original poster: I have owned both - a Pass Labs INT-25 and a PrimaLuna EVO 100 integrated, with my Klipsch Heresy III. In short, I preferred the PL. The INT-25 sounded a but too 'meaty', not transparent enough, it seemed to fill the speakers too much with sound - if that makes sense. The PL was a little rounded off at extremes, but provided an average more pleasant voice, with enough dynamics and an enjoyable old-fashioned timbre. I also drove the H3s for a few days with a Bow Technologies Wazoo - not so dissimilar to a Pass - and the result was the same: a feeling of 'too much-ness'. Hope it helps, just my opinion.

Large toroidal, full dual mono circuit and 4 transistors per side. Decent phono stage. 50W RMS. If one can get past its 'commercial' looks and pretend it's a boutique amp, a successful buy.. 😉

Hi, it's all in a finish they call champagne; the front panel is thick and the knobs apparently made from solid. Good build, in my experience.

It may not compare to the posh amps I see here, but I am using a TEAC A-H500i with my Klipsch Heresy IIIs currently, and I am extremely satisfied with the combination. The TEAC is a serious amp, dual-mono circuit, toroidal transformer and solid build. It's pleasant to use, sounds fine and hasn't made me regret the Pass INT-25 I used to own. It costed €220 and caused my lost of interest in expensive audio.

The Esoteric K-07Xs has gone, a TEAC PD-H500c came. A Technics SL-1510 completed the system. In another room - or another house, the Heresy will go back on their slanted bases. The TEAC electronics sound magnificent with the Klipsch, and TT, cartridge, CDP and amp costed me €700.

Hi, sorry. but I missed your post because I don't check the forum often. In the end, I tried to put a few things together - some watts, a preference for older Japanese looks, a mid-size enclosure, a phono stage. I chose a TEAC A-H500i because I have had the lesser model, the H300, and it was a very good amp for the modest cost. I was lucky, the Teac is a very competent, unsuspectedly fine performer. It drives the Heresy well and ticks all my boxes. It costed me €220 and is, so far, my Best Buy ever in audio. Max

I know that Paul Klipsch said not to keep Heresy on stands, but the sound in our room is definitely better this way, for now. System is presently: Esoteric K-07Xs, rega P2, TEAC A-H500i, Heresy IIIs. The TEAC amp is amazingly good, it drives the Klipsch with ease and an open, dynamic voice. I really wonder what more could be asked for. Especially since I paid €220 for it and it's mint. Best Max

Randy, The Wazoo was very good with the Marten Design Miles II's, but I like it less with the Heresy. It is basically a power amp with an input selector and a passive volume control. I too believe that a good preamp makes the difference. I admit it's weird but what makes me dislike the Wazoo a little is a feeling of excessive 'presence' of the soundstage and voicing. I am investigating Yamahas, but most models are discontinued so I'll take a look at the rich second hand market. Thanks, Best Max

Hi Randy, I currently have a Bow Technologies Wazoo, it's a 50W MOSFET unit. It's sort of sharp and too much 'focused' for my taste, plus its bass is not very extended and a little 'bumpy'. It was very good years ago with Marten Design Miles Its, but it doesn't seem to gel with the H III. I may consider the Yamaha A series, thanks for the hint. It's not the first time I read good opinions on the pairing. Max

Hi Bruce, thanks for your post. I have read enthusiastic opinions on 2A3 amps, and a guy not far from my place is selling one and would take my SS integrated in. I may go for it and put a lid on my quest.. Best Max

Ok, I realize that I won't have any useful opinion/indication unless I give some more informations. Our living room measures 3.85 mt. x 6.50 mt., ceiling is 3.05 mt. The room is furnished, two sofas cornering each other, a large carpet, a grand piano, a large bookshelf. The right-hand 6.5 wall opens onto a 3.5 x 3.5 mt. dining space. Three French windows, with thin curtains against the glass. The Heresy are placed on the short wall opposite to the bookshelf. They fire across the 6.5 mt. dimension. I mainly listen to acoustic music of any kind with a preference for small-groups jazz, classical, songwriters. I never listen very loud. Most of all, I come from years of swapping, experimenting, spending! I am very tired and am looking for an integrated amp with the minimum useful power to complement the culture and concept of the Klipsches. My source is an Esoteric K-07Xs SACD player, I'll add vinyl to the setup. It doesn't have to be a modern, costly unit - anything will go if it matches the Heresy well. I'm grateful for any useful tip, options are too many and I cannot simply borrow the whole world a piece at a time to demo at home. Regards Max

I've heard my Heresy IIIs with a Pass Labs INT-25, good but not excellent; with a PrimaLuna EVO 100 integrated, very good; with a Bow Technologies Wazoo, good but not very good. I read that you can use them with 5Watt tube amps, with 100Watt solid state, with SE triodes and with MOSFETs; they seem to be content with a fistful of good watts and with large power stations; I can't make up my mind as to which amp to look for. I cannot demo anything at home; that is why I am collecting other users' experiences. Thanks.
