Well, I listened to the whole thing last night via the main system and it sounded brilliant. Saturated to hell or not.
Not my music style - I'd never listen to this sort of stuff usually - but it is brilliant. Will listen again.
There's plenty of stuff that is saturated to hell that sounds OK to fab in practice, IME.

Hello from France. Thanks for this very interesting thread .I bought my apogee calliper signature in 1990 and enjoyed them a lot since that time. I just wanted to tell that the duetta are better but in a small room the calliper stand well. In the review made by M Colloms in Hifi News in 1989 he said that it was the same sound than the duetta , but this last one has better bass and scale,...
too often people buy loudspeakers which are not ideal for their room and the result is compromised.
My next upgrade will be upgrading filters and make a reinforcement of the frame and naturally a change of foil.

Gilles, this is of a lot of interest to me as a Nat amps afficionado. I'm currently running SE2SE 211's rated at all-Class A 60W/ch, but would be happy to move up to Transmitters at all-Class A 120W/ch.
In yr opinion, is a single pair of Transmitters enough to run Graz Duettas, or is my basic minimum to biamp w/a second pair?

Apogee speakers work best bi amped, but for the Nat amp I think the best way is to listen to User 211 system to make your own choice. With apogee some swear by big ss amps and other are satisfied with valve so it's a personal choice. Take your time.
I have unfortunately never heard the Nat amps.

Gilles, my decision on going Graz Apogee Duettas starts and ends w/the viability of running them w/Nats.
If I go Duettas, I'll upgrade my SE2Se's to the Transmitters.
Can you clear up something? That Studio Grand owner is running the bass panels AND ribbon tweeter off the onboard amps. That leave just the ribbon mids. So why does he need the second pair of Transmitters?
Or is the onboard amp powering the cone woofer box AND tweeter, one pair of Transmitters the ribbon mids, the other pair the big bass panel?

Justin, sorry if I appear to be stuck in a groove going 'round and 'round on this. My SE2SE's just fine as are. Suit my Zus, and any possible horns choice just perfectly.
Transmitters only if I go Graz Duetta. And now I've seen them in use on the Studio Grands, my mind is more at ease.
Transmitters purchase will only happen if I go Duettas, or Omegas/Amphtrions.
It was just seeing TWO pairs of Transmitters that I was curious if the Duettas would similarly benefit.

Must admit I was surprised to see it. The heat output must be very significant...
At a guess I reckon he has one pair on the bass panels and one pair on the mid range ribbon. They must be working very hard though. The Grand is 84DB and 3 Ohms. In-built Krell amps do the bass and the tweeter ribbon (WTF?).

Transmitters were better than se2ses anyway, they were a later development - not just for more power. And they can be run both at high power and low power, so can the Magma. You have to throw a switch to move from 40w to 160w on the Magma.
I'd like to read the Miller Audio Research technical info on the Transmitter. The Ken Kessler review talks about it being 80 Watts... why - is that the low power mode - doesn't say anything on the website about 80 Watts - 30 in low power mode. Don't NAT claim 120 Watts? Is Ken saying 80 cos that's what the tech tests came up with?
Also, Telefunken did an RS 687 valve that looks like an alternative to the Philips effort, and there is a cheap Russian variant on ebay - very cheap - £40. So you can roll if you want - if you can't source the Teles at least the Russian ones are available.

So Justin, the Duettas are a much easier amp load than the Studio Grands? If so, Transmitters should be the ticket. If I go this route, I can add a second pair in time. Is there a separate outboard x/over box that would accommodate two sets of amps in yr Interstellas?
Re the shattered Phillips tetrode that Kessler managed in the test - let's put it this way, I wouldn't let Ken handle my shopping, let alone my hifi - do we remember the infamous destruction of the Thales LT arm he somehow wrought? The guy is positively lethal LOL!

I've just been reading the Transmitter tech results done by Paul Miller of Hi-Fi News. The Transmitters are 80 Watt amps at 3% distortion - no question about it. They can probably manage more at much higher distortion figures I expect. My 211 monos are 80 Watts, but can manage a lot more for unquoted distortion figures - which will be high.
I also just re-read the HFN Analysis Audio Omega review which is far from kind, but ultimately everything I read ties in with my subjective experience. Namely - they are quite severely rolled off in the treble, and that they lack dynamics. Given this, I feel it really makes them unsuitable for electronic, reggae and rock music. However, I think they are fabulous for classical and other, less dynamic forms of music.
That said, a friend and avid MBL user (totally into classical) thinks they suck. Go figure!
Re KK's exploding valves - they can't have exploded. They might have imploded, but I think that is unlikely without some form of provocation!!!

I have not read all the posts but the discussion seems to be hovering toward a <100 Watts tube amplifier on an Apogee Full Range. I would like to hear that to be convinced of how good it would sound. Color me very skeptical. 84 DB and low impedance are not a great match for that kind of aplifers in my book.
