Hi Henk,

Do you know how loud he likes playing music, sounds like it would run out of steam?

I'm OK.

It's just that some idiot in a car knocked me off by bike 4 weeks ago,and broke my left collarbone.

But I'm almost back to normal again, all is healing well, so I don't expect any lasting damage.
It did however trash my Paris travel plans....

Wish you all the best with that Henk!

With Apogee isn't it so that it's current that counts, not so much watts?

Mend well Henk

may I enquire, does the mending process makes your chuckle....
30 years ago, I too came off a motorbike (front wheel encountered a loose car headlamp in the road, while I was banked over coming into a roundabout... whoosh) and found that I couldn't stop laughing

after your beautiful work on Apogees, are you tempted to re-model this time
(incorporate shock-absorbing section to the collar bone?)

wishing you Happy Christmas Henk

and to all in our Apogee community

Hi Guys,

Just spent 2 wonderful evenings with:
AudioNote G1000
AudioNote Kagura (pair)
Studer A80
2 refurbished Diva's.

Final verdict: The best apogee sound I have ever heard. And more than loud enough, as a matter of fact I asked for the volume to be turned down a bit on a number of occasions, and I do like to play a bit loud myself, just ask Kees or Stanley:)

I had nothing to add except superlatives. This set-up clearly delivered the most stable, deep and wide image I have ever heard.

How much of this was caused by the Studer? Quite a bit. I never asked what digital stuff was used (we played a number of files using Jriver). One thing was clear: The A80 trounced the digital stuff in all respects. (except noise floor, of course).

He has one recording of the Sacre Du Printemps by Solti which is especially fantastic, so I heard that recording twice:)

On the A80 we exclusively listened to pre-recorded "master" tapes, I've forgotten where he buys them, I do remember it was a small Italian company that specialises in low-volume direct copies of master tapes.

Not really an affordable option (at least not for me!) but I'm very happy to have had this experience.

Hi Henk

Hell finally froze over :lol:
Tubes on Apogees? Excellent sound? Loud enough? :mrgreen:

I think the labels name is foné

Cheers,
Christoph

Ah, those Diva's with all Mundorf Supreme Silver-Gold-Oil caps. Never heard them but I have some imagination. Must have cost a fortune (but peanuts compared to them amps).

If you can playback on a professional tape machine from master tape copies, not much will beat it. Often, consumer audio media has gone to many steps, each transfer opposing a slight loss.
Remember how long ago Kipdent had bought a tape machine and audiophile tapes?

Earlier I have mentioned you can get DSD audio from e.g. Channel Classics which are a straight copy from the master. With the right playback equipment you should have a similar experience.

Oops, went a bit off topic above.

Advance Acoustic is a French designed China build amp aimed at the budget Hi-End user.
I have experienced my MAP-303II on Magnepans, the Stage, the Ribbin Wall Speakers and now the Calipers (and some other speakers as well). The Calipers are the heaviest load. The amp does it. The volume knob needs to be turned up much more as with any other speaker. On the Calipers I run it in auto, this means it is in Class-A for as long possible, then switches to Class-AB. With the Centaurs, on a listening session I put it in Class-A. (period)
I definitely hear a difference between +20 and +10, where at +10 it is more at ease. (the volume goes from -64 to +64)
It may be well behind the Krells and Brystons and whatever of this world that I have never heard, but it does the job, never missed a beat -knock on wood- and I am happy with it.

I've always been a big fan of Balanced Audio Technology (BAT). Currently running my Duetta II Signatures with a VK-600 with Bat pack and a VK-6i tube preamp. Prior to this setup they were driven by a VK-500 with bat pack and a VK-3i tube preamp. Lots of headroom and a great sonics match.

I'm using a modest system to drive Duettas, which were rebuilt at some point.

A Classe Ca 101 drives them remarkably well, and the previous owner agrees. I'm not sure why, but my amp requires more gain with the Duettas than with the Calipers I had previously, but it runs cooler. I've never felt like it was running out of steam and I always chicken out first. Mind you, if I had a Bugatti, I don't think I'd ever find out if it did 200 mph.

I also use a Classe CP 35 preamp and a CDP 10 cd player. Cables are Nordost Blue heaven. The previous owner reckons I'm getting as much out of the Duettas as he did, although I'd put a lot of that down to my room acoustics, which seem to let them sing very well.

Maybe the Duettas are 4 Ohm and the Calipers are 3 Ohm.
This would explain why you need more volume setting to achieve the same sound volume level for the Duettas but the amp still runs cooler.

I've just been trying out an Acoustic Energy sub woofer. A 500w amp apparently, and a crossover for bass frequencies if connected between pre and power amps. As far as I understand it, the idea is that the Duettas won't demand as much current from the power amp and won't have to work at the bottom of the frequency spectrum. An easier load all round?

Perhaps someone with a better grasp can help me out here.

The sound is exceptional, by the way.

You pretty much have it figured out. The trick with subs, are to get ones that are quick enough to keep up with the speed of the Duetta's panels. After that, it's just the usual xover point and gain matching issues that you always have with subs. I have heard that using 2 subs is best.
Good listening,
