I hope Mike delivers what he says he will. Seems well intentioned but sometimes he reminds me of Mark Schifter with constantly changing variables.

:rolleyes: yes I agree that it can get confusing at times. Having dealt with him before, he has quiet the ambition and intention to build great products at reasonable price. Will know next week :)

I am getting a pair of them (monoblock configuration) hopefully sometime next week. for the price of admission its worth the shot and who knows what newer tech brings in. I figured that if it doesn't work for me, I can put it in use in my HT system happily :)

I'm looking forward to this.

Well, if that's anywhere near Tampa "Bay" area, make sure to hook up with either SAS or Sarasota so we can hear the mighty MIVs...if they materialize.
 
AJ a significant number of them have already been delivered, assembled and are breaking in so they have materialized.

Interesting thread...

I diy'd ncore monos and very much enjoyed them over my tube gear. My pre was a Bent Audio Tap. My system never sounded so good.

I then sold them to buy a JOB225 amp. THAT was a mistake! Sold the Job and bought a MW KWI-200 Integrated. Returned that to Dan Wright and purchased a Wells Audio Integrated.

Ended up selling the Wells and purchased Colin's Nord One Up Monos which I pair with a TLA MZ2 Pre with NOS Tubes. Pretty happy again.

Yes...I am going to try the new AS1200 from Mike. For the price of admission, why not?

Full disclosure....I am a professional classical musician who has played in symphony orchestras for over 37 years. This can really be a curse when combined with looking for audio pieces!

I recall reading a similar post many years ago from a conductor only he was tauting his speakers. I was researching a speaker purchase and he owned Maggie 20.1's. Helped me decide to get my 3.6's: I don't think I will ever part with them. My dual Nord One-ups make them sing. I may try Pass labs one day but I am not sure I want to tolerate the heat output when it is 40 degrees Celsius in the summer here.
 
I have almost 75hrs on them and they are very promising so far (and a bargain at the same time). For folks who are interested, I posted my initial impression on AC.
 
well, I am not surprised a bit :cool: Technology advancement and innovation always leads to good things - today B&O is edging out but I am sure Hypex has something up its selves that's going to turn the tables at some point.

the input buffer in the Nord can be improved quiet a bit from what is it today. I have to check but I think I might have the rec C board.

Don't mean to rain on the parade, but B&O has no technical advantage over the Hypex. In fact the opposite may be true. Yes, I've tested both AS2 and NCores extensively, including some with a bit more scientific rigor than someones purely subjective anecdotal experience with a large dose of expectation bias and the hype machine running full bore. It would also be sort of helpful to compare modules with similar power output (not to mention a slew of other controls to prevent self deception :)).
Both AS and NC are very very good and largely transparent into any reasonable load if properly implemented.

cheers,

AJ

Cool. So what was your result ? Who won ? If Hypex, can I also get one of those amps as well ?

That might possibly happen someday with the Merrill Veritas but I don't have it now.

What exactly you mean by "properly implemented" ? Care to elaborate ?

It means both are sold as "modules", so one still has to provide input, output connections, etc.
In my implementation they are directly coupled to the drive units, there are no passive reactive components between. They become a part in the overall total circuit design.
Btw, in my previous interactions with Mivera, it was immediately obvious he had zero knowledge of basic (High school) level physics, much less EE>, nor had he performed an electrical measurement in his adult life.
IOW, he's the perfect "audiophile" designer.:rolleyes:

Neither. As I said, both proved to largely transparent (as far as sonic "signature") goes vs the other. The "winner" for me would depend upon power requirements, cost, reliability, etc.
No question that for the money, the 1200AS2 provides a boatload of clean power. For my current needs (i.e. directly coupled to one driver) it's overkill, but never say never. I could see where it might be alluring for folks with low sensitivity, power hungry passive speakers.

cheers,

AJ

Don't have any but it's conceivable that could create some misbehavior if pathological enough.

Have you ever played around with the output inductor , i had theorized this was the cause of timbre issue not heard at 8 ohm but when at 4/2 ohm operation. In wanting to build a full low Z operational Class-D , thought it best to lower the PSU voltage and possibly play with inductor value , i wont have any need for 400-600 watts at 8 ohm, but would like 400 @ 1 ..

The B&O current capabilty look interesting here ....
