Weltfaul Posted September 25, 2021 Share Posted September 25, 2021 Hi. I drive my Heresy IIIs with a PrimaLuna EVO 100 integrated, a 42W, push-pull tube amp. The room is about 40 square mt. A guy came visiting a few weeks ago to demo them, brought a few CDs along; all music was rich in texture, bass and ambience. He liked it to be played louder than I am used to, so I could appreciate the Heresys' powerful rendition. Anyway, my feeling is that the Heresys can digest many more watts than their declared sensitivity suggests are enough; and that a powerful SS amp would make them flourish better than my more domestic valves. Anyone with personal experience of Heresys powered by powerful solid states please? Thanks, Max Quote Link to comment Share on other sites More sharing options...

If you want to have so fun once in awhile, buy a QSC RMX 850 or so other cheap amp and know you can easily max them out with safety filters in place at the sacrifice of sound quality. You have an EXCELLENT amp, keep it. The guy that came by might need PA speakers for his mains, doesn't seem like you do. 1 Quote Link to comment Share on other sites More sharing options...
macHewson Posted September 25, 2021 Share Posted September 25, 2021 I have a Cayin 34 with 32 Watts and I had Hereseys before my CW and both can be cranked without any Problems, so I think with the Primaluna you have enough power to play loud and the Primaluna is really a good amp too. No need for an SS IMHO. Those speakers are just perfect for Tubes.Gesendet von iPad mit Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
Weltfaul Posted September 25, 2021 Author Share Posted September 25, 2021 Hi, thanks to both. WCD, yes it's what the guy liked, but my impression is not only based on that single listening sessions but on the fact that the Heresy are a sealed box design and that they can sustain up to 400W of power; this seems to suggest a loudspeaker system with an optimal volume level higher than that of more 'domestic' units. But yes, I am aware that the PrimaLuna is a very good amp and that is why I am extremely reluctant to consider a replacement. My question was about the experience of people with a solid state, powerful amp with the HIIIs. best, Max Quote Link to comment Share on other sites More sharing options...
MEH Synergy Posted September 25, 2021 Share Posted September 25, 2021 I bought a Parasound A21+ for my 104 dB (in Free space) JBLs. Why? 500 wpc. The hell is the matter with me right? First 5 watts are in class A, that's where I spend most of my time. Was worth it to me to have unlimited power and class A often. 4 Quote Link to comment Share on other sites More sharing options...

If I played your speakers through my parasound a21 amp and even tried to touch the limits that you could sustain (unless you are used to 140 dB car audio or 130+dB concerts ALL THE TIME) you would be driven out of the room far below 100 watts. 2 Quote Link to comment Share on other sites More sharing options...
MEH Synergy Posted September 25, 2021 Share Posted September 25, 2021 If you need more, you NEED KP250s. Just picked up a pair and upgrading the tweeters to Dave A MAHLS as we speak (waiting for them to arrive). Those, along with my dual proted 18"s, I can almost guarentee that neither you, nor your buddy could take it at more than 50% volume sustained 1 Quote Link to comment Share on other sites More sharing options...
Ole Dollar Posted September 25, 2021 Share Posted September 25, 2021 I'm using a 40 watts per channel 6L6 based amp with Heresy 1s and a sub-woofer. Before the 6L6 amp I used a 3.5 watts per channel amp using two 6BQ5 tubes. The increase in power with the 6L6s was pretty noticeable at higher volumes which I almost never use. I agree with @Westcoastdrums I'm living in the first 5 watts. I would have moved back to the smaller amp but the larger amp has better sound quality everywhere it operates.

MEH Synergy Posted September 25, 2021 Share Posted September 25, 2021 I could likely EASILY live with a 5 watt or less 300b... BUT, I have my preferences and I don't like soft and romantic. I love crisp, modern, dynamic, slamming tight bass and as good of a spatial and palpable midrange as one can get. That's how I ended up with my choice. But believe me, anyone local in socal is willing to come listen, as the system is turned up, CRYSTAL clear to PAST concert levels (I'm less than 15 feet away from the speakers and the subs are QUITE serious for this room). It gets extremely silly quick and if you hang around past, I will smile and leave because I can't take it. 2 Quote Link to comment Share on other sites More sharing options...

MEH Synergy Posted September 25, 2021 Share Posted September 25, 2021 Don't tell anyone as it blasphemy here, but I sold the first watt m2 as the parasound a21+ killed it at low volumes and easily DOMINATED it as the volume rose. Same speakers, cables source, position. All the same. Quote Link to comment Share on other sites More sharing options...

macHewson Posted September 25, 2021 Share Posted September 25, 2021 I had a hybrid Magnat with more power before the Cayin, same price range, I do not want to go back. I am more into relaxed listener but sometimes I like it loud too but with keeping the musicality. So I went the other way instead of buying like a 5k Yamaha 3000 to get what I want, I went for the Cornwalls and kept the Cayin. The CWs are filling my room with music whereby the Heresey did bring the music into the room. I would have to force them too much in this case. My experience now is that it sounds loud, even when I play at low volumes. Neighbours are happy Gesendet von iPad mit Tapatalk 4 Quote Link to comment Share on other sites More sharing options...
MeloManiac Posted September 25, 2021 Share Posted September 25, 2021 I've driven my 1972 Heresy speakers with 3.5W p/c (TubeCube), 12Wp/c (Leben CS300), Harman/Kardon 430 (twin engine, 25Wp/c), and modern Denon and Marantz amps ((40W p/c). In my experience, it is not the Watt that determines the sound quality, but the quality of the auditory circuit. With sensitive speakers, my CS300 with 12 Watt per channel is more than loud enough, even in a large space. But then again, I like to listen to details at low volume, close range. I fully appreciate people who are after a more visceral experience and want to feel the music, literally! There is one thing I don't fully understand. My 1972 Heresy speakers specs are 100 Watt (peak 300W), while in 1972 there were very few consumer amplifiers with this level of power. Currently listening to Iron Maiden's new album, volume nob at 12 o'clock, and it is deafening... 2 Quote Link to comment Share on other sites More sharing options...
michaelwjones Posted September 26, 2021 Share Posted September 26, 2021 I have a Conrad Johnson MF 2550 SE with 250 watts per side used successfully with both Heresy IIIs and LaScala IIs. Sounds great; never run out of headroom. On the other hand, my 5 watt Gaanam and my 12 watt 300B sound great, too, just different.

Joecoulson Posted September 26, 2021 Share Posted September 26, 2021 (edited) I too have the Parasound A21+ with the first 5-6w in pure class A. the sound is rich and warm and I do not miss my tube amp at all. Any level listening. Either barely audible or or ears bleeding, this combo (CW IV’s) is stunning. All types of music. I did keep my sub in the mix as I do like to feel bass below 30hz which I don’t think any Heritage speaker registers properly (correct me if I’m wrong) but very happy SS user here.

SWL Posted September 26, 2021 Share Posted September 26, 2021 I gotta have it all. Rolling amps and preamps is a sport around here. Depending on mood etc it varies from low powered tube to high powered pro-amps to low powered solid state to high powered vintage solid state.The results from different combinations of tubes, interconnects, power cords, speaker cables, speaker positioning, different rooms, different acoustic treatments and on and on seems endless.....and fun.Then there's DAC's.....Sent from my SM-G991U using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

I'm usually hanging out around 95db peaks but I have measured up to 105db peaks in my room before, when I was drinking lol. Quote Link to comment Share on other sites More sharing options...
Dave A Posted September 26, 2021 Share Posted September 26, 2021 I stopped searching when I got a Crown XLI800. With efficient speakers they will run you out of the room and I have never turned them up to even 3/4 of their potential. I have had much bigger output amps but none have sounded better. I have no experience with tubes because I am not interested in them. 2 Quote Link to comment Share on other sites More sharing options...
