$$$Sensitive Speakers with $$Amps?


I've read a recent thread, and a Six Moons review for recommending certain amps who's price tag falls short of the subject loudspeakers. For example, Red Wine Audio 15 with Rethm Maarga speakers.

My area of focus is with sensitive speakers being driven by low-watt amps. Are there really super values out there for these type of amplifiers, or do the typical spending rules apply?

Kenneythekey, I'm impressed in the most incredible way by your willingness to travel all the way to the East Coast to hear the Hornings. Indeed, the bravo goes not to me, but you! It's exactly THAT kind of passion that makes this hobby so wonderful.

With RMAF so close, September might not fit the plans of either you or Jeff. But if you can swing it, the annual Feast of San Gennaro http://www.sangennaro.org/ is a very short walk, and something not to be missed. After San Francisco (never visited, but it holds the reputation), New York probably has the most interesting Chinatown in the country, and also sits right there. Still, the sight of the Brooklyn bridge right there at Jeff's place will likely move you in a big way.

Since you'll be out this way, if you care to travel 1.5 - 2 hours south to Philadelphia, you're welcome to give my Hornings a listen as well. Since our rooms are so different (brick/hard floor vs. drywall/carpet), the sonic presentation would likely reflect that.

Mapman, I'm not a low volume guy, but understand that's more the rule than the exception. To answer your other question, with the backloaded horns I have been around, yes, some SETs can do more volume than the more familiar push-pull amplifier.

Again, a sort of "coupling" that transcends wpc ratings may come into play. We know it's not electrical impedance in this case, but I don't think the word "impedance" in a different sense of the word misses the mark by far.

Another way to picture it could be the ability to propel the air that exists through the long length of the exponentially expanding horn forcefully enough so that it meaningfully adds to the impulse propelled from the surface of the driver itself. Obviously, I haven't worked it all out, and I've yet to meet someone who can explain it to me. It might be when comparing SET, PP, and OTL amplification, we're dealing with something like the whip versus the club; both of them powerful, but of a profoundly different nature.
Trelja,

Well, I haven't heard the Aristoteles because they haven't been at the RMAF show in Denver when I've gone, but got to hear their big brother the Eufrodites. I also have not heard the Rethm Maargas, so it makes sense to go to NY to hear both.

I'm sure that Jeff and Gideon can recommend amplifiers that won't break the bank.

Thanks for the invite to PA, but it will most likely be a short trip. My room is brick, plaster, and hardwood floors, so is that what you also have?

My wife and I were in NY (Queens) for ten days in the old neighborhood. Unfortunately, we had to take care of family business and could not get around, however, we feasted on local Italian every night. Yum.
It seems to make good , hard nosed economic sense, to go for High sensitivity speakers and low powered amps. High sensitivity speakers don't need to cost more, the cost maybe is reduced base output. High output, particularly with tubes, cost money, at least for reasonable quality.

I agree amp noise is an issue with plus 100db sensitivity horns, but personally, I have never liked horns. The sweetspot for me, is mid 90's, conventional box speakers. They sound great with as little as 10watts, but 20 seems a better, all round choice. My Dadalus DA-RMa speakers sound wonderful with the 20watt Ayon Spark and cheaper options like the Almarro 318B
Thanks David.

I've been living with conventional mid-nineties box speakers, well, since the mid-nineties. I have gotten years of enjoyment from them. There were multiple rooms with Dadalus speakers at the RMAF 2010 show where I also heard the Horning and Aspara speakers that Jeff was demonstrating.

I'm not a classic horn person, as they don't quite fit my ear. I try, and try again, but I can't fall in love with Klipsch, for example, and Jeff's Aspara offering did not quite do it for me either. I also struggled with "all" the box speaker offerings at the show. I want to blame the rooms somewhat, but my disappointment remained consistent.

For whatever reason (hybrid?), I fell for the Hornings. I must admit that Jeff had a large suite and he's a wizard at setup. Still, I can't get that sound out of my head while all the other sounds at the show have long faded. It was the haunting and intimate spatial presentation which won me over. Not as haunting, but intimate, open, and refreshing, were the Voxativ Ampeggios I heard in Montreal 2011. Equally refreshing in Montreal were Devore's Orangutans. However, with all of these choices, I didn't miss LF extension as much with the Hornings.

I'd like to get back to amplifiers, and have added the < $4K Almarro 318B to my list. Here is the revised list, so far:

Loudspeakers:

Horning Aristoteles
Rethm Maarga

Amplifiers:
Note: I realize some models will be integrated, so a plus IMO.

MiniWatt N3
Red Wine Audio Signature 15
Yamamoto A-08S
Déjà Vu 2A3 (Under $4K?)
Audioprojekte CA10
Traformatic Aries
Triode TRV-A300SE
Almarro 318B
Alkso, try out the sleeper and giant killer of the year amp, the TBI Millenia. Their is a review of this at TNT audio here on the net. When you hook up a 24V battery system to it, you will hear more detail than you have ever heard before, while staying very musical.

A friend of mine has the Rethm Trishna's and he prefers the TBI over his MiniWatt N3 by a fairly large margin.
