Roy Gregory Names Clarisys Atrium/VAC System Best in Show

[morricab]

What’s the impedance, and what’s the lowest it drops to

They use transformers so that the impedance the amp sees is not very low.

102db measured how Ron ? Thats sounds very high ..!

A whole lot of very high powered N52 Nd magnets...

 

[morricab]

102dB on horns i would never indeed use SS amps (but I will once I get the specially designed SS amp for horns)

You're going to drive your Tobian speakers with SS amps?

The website states 101 dB. It's a 5 ohm speaker, but it was measured at 2.83 volts for an 8 ohm speaker. The real value is closer to 97-98 dB/1 watt, which is still an excellent value. So please measure carefully and avoid cheating.
2.83x 2.83/ 8ohms =1watt
2.0x 2.0/ 4ohms = 1watt

Equivalent sensitivity is higher for planars

 

[DasguteOhr]

Equivalent sensitivity is higher for planars

Your room can change this depending on how damped it is. Efficiency measurement is a fixed physical quantity that can't be cheated.is measured in an anechoic chamber 1 meter distance.

What does this mean, while Clarisys were playing orchestra the French horn section went up to 102db

Correct

 

[bonzo75]

Correct

Wow am I an accurate Ronpreter

 

[bonzo75]

Also, were trumpets and trombones confused with horns?

I don't know the exact methodology, but I do know that it is a standard industry practice methodology.

Okay, let us know how it goes and enjoy!

My comment was broader. I would not use a solid-state amplifier on a 101dB sensitive ham sandwich.

Yeah - cheese might melt faster

Not to troll this thread but yes - very special SS amp is being finalized as we speak specifically designed to drive highly sensitive speakers ie horns, so I intend to use it for the sake of fun - ie swapping with my also inbound SET amps. Can bring it once to your place to try it out on your horns.

That would be fun! What SET is inbound? You might also want to try my TriodeFet amp on your Tobians at some point...

I would love to try some of the FirstWatt amplifiers on my speakers. As someone who reports on the industry and is a dealer, I’m surprised by your absolutist approach. Aren’t you even at all curious? Nothing wrong with such a stance. I’m just wondering why you have no interest.

Very true...as there are SET and PP tube amps there are also different kinds of SS amps as you rightly mentioned and one of these is FW especially the some of the SIT ones...

And in the overall context I'm sort of puzzled why this narrative is being pushed over and over again that panels are now super easy to drive with tube amps? I personally heard Studio plus in two different setups and on the first occasion in setup no.1 they've been driven by tube PP amps (big ones) with tube pre and tube DAC. They sounded OK but nothing more than that considering the price of the gear. On the same occasion and in the same setup we replaced the tube power amps with the monster SS amps and the result was like the gates of heaven opened - amazing difference and amazing lifelike presentation - just mind blowing.
If I'm not relevant, go and see the thread of @Thundersnow who owned and used for prolonged period of time on his panels (Studio Plus) huge SET power amps with "good" results but only when he placed monster Karan SS mono blocks with 2kW per side magic happend. In his case tube DAC and tube pre are driving the Karan amps. BTW this was system No.2 I heard few weeks ago and yeah - it sounds amazing.
So, in nutshell can you drive them with tube amps - yeah; will they pull out absolute best of them - I'm 99.9999% sure not at all - until someone proves me wrong ...even with their on the paper sensitivity rating of 102dB (for that rating go and prove it with 3W 2a3/45 SET amp - should work like a charm....ah yes you can't...)

Tobian 300b...we'll agree for the meet up...

 

[Kingrex]

Isn't Clarisys a ribbon type speaker? How could it win an award???? Or be best of show. Steve said that type speaker can't make any "felt" bass.!!!! If it doesn't make bass, who could like it.

This is what i wanted to say after listening this sytem in munich
