VAC Renaissance 30/30 driving horns ?

24.4.254.50

Posted on April 30, 2000 at 01:00:47
Anyone tried the VAC R 30/30 .III driving horns or high efficiency speakers ?
Seems a little more dynamic than the usual 300B SET.

I'm driving Klipsch La Scalas with Welborne Laurel's and the combo
is PLENTY dynamic. It's not the amps, it's the speakers that present a problem to most SET's.

With regards to the "usual" 300B amp: there are probably more people driving big horns with McIntosh than anything else; big dark Khorns in the corners and Macs glowing blue in the bookcase, nice package. It's just that these guys settle down and listen and ain't obsessive like us goons here :-) I've half a mind to chuck the tube stuff myself and get some SS Macs, they're so pretty.

Just because you have tubes does not mean you are obsessed. There are
diminishing returns in all things. The VAC amp and the CAR speakers
should be a killer combination driven full range. Why complicate things further with bi or tri amping?

I have heard the VAC 30/30 on a pair of Innersound Eros and it sounded detailed, rich, and dynamic--a very musical combo. I would love to hear them on my AG Duos. I am alternating between Cary 805C amps and a parafeed 45 on my Duos now, and it's amazing how good the 805C can sound. It doesn't have that magical musical expressionism that the 45 amps seem to do so easily, but it's close. The 45 amp, at less than 1/10 of the power has deeper and more detailed bass, so power & bass don't necessarily equate.

can affect the bass on the Duo, but "deeper" bass than the 805C? How can one tell such a thing with a SS powered subwoofer?

Hi Rich,

Good question.

Steve Harris in his HFN&RR Review stated it thus;
"With its very high published sensitivity, the Avantgarde is eminently sutable for small valve amplifiers; 10 watts single-ended-triode amplifiers will easily go loud enough. Paradoxically, the better subwoofer actually makes the UNO more demanding on amp quality. The sub has its own amplification and so makes no real power demands. However, the subwoofers amplifier cannot make something out of nothing: if the bass quality of the chosen external amplifier is poor, you will certainly hear it. With some valve amplifiers, in other words, the subwoofers qualities will be wasted."

In this case, it may not be bass quality so much as absolute extension. Given the very high impedence of the DUO sub's input, virtually no current is required to drive the bass. So while amp A may make useful bass power (in terms of driving an 8 ohm speaker) down to 30 Hz then roll off (sensible when you've only got a few watts in the first place), amp B may produce 8 Hz bass with insufficient power to drive an 8ohm woofer but quite enough for the Sub's high impedence input.

Les--I meant that people who post here are obsessed. Bi-amping tastes good, passives are the complication.

Emmmmmm..... Quad amping even tastes better. I'm thinking of a Mac amp to drive my bass speakers. Ever hear a 2105?

As a VAC 30/30 owner, I've been pondering this question as well. I cannot find anyone anywhere who has tried VAC REN/Horn combo, and I would love to know! As far as high-efficiency speakers, I currently use a custom prototype box speaker with 92 dB efficiency, biamping the bass with solid-state. Basically, 92 dB is Plenty for the little VAC 30/30, as I have NOT been able to clip the amp yet. By the way, my new TG HSR-i squared power cord is showing me the true wonders of the 30/30 (after a LONG break-in)and might I suggest you try it on your VAC when you get around to it. You won't regret it.

Horns and SET's are a wonderful match. The Klipsch Heritage series
in particular. With some simple tweaks and crossover mods the cannot be beat for the money. Especially when purchased used. Klipsch's were voiced with 2A3's.The crossovers were changed for the worse in the seventies with the advent of the muscle amps which were smokoing tweeters. These are Sleeping Beauties, and you do not have to sell the house to get them. www.klipsch.com check out the BB.

The main amp drives the sub amp in the Duos, so the extension, detail, tautness, etc. of the main amp is easily heard. What's lost in the main amp is lost to the subs. The lower powered 45 goes deeper, has more detail, and believe it or not, gives better pace & ryhthm ... at 5% of the power.
