Considering Gryphon Diablo 300 "OR" Simaudio 700iv2 ???

Audiotroy... It is an audio forum not a Police station... To answer shortly: All tests were carried out to ISO and EN standards :)

T+A pa3100- nice amplifier, but too polite for me. Nowhere near the dynamics and control when compared with diablo. Low end was much worse.

Vitus-again nice amplifier, but not as natural, controlled and dynamic as diablo.
Both had much worse soundstage too. 

Fact 12 are quite difficult to run, 84db and transmission line will test the best amplification out there.

If tested on a highly efficient speakers it is likely the differences between diablo and other amplifiers would be smaller.

But don't we want an amplifier which can run any speakers on this level?

Thanks

You just described exactly what I heard comparing the T+ A PA 3100 driving Magico A3 speakers to the Gryphon Diablo 300 driving A3 speakers. In addition, the Gryphon was more open and detailed to my ears.

“”But the cables...”

LOL

Actually there are a few posts on another forum,in one an owner of the 3100HV who tried some Furutech cables and was very happy that the cables gave the amp more dynamic impact
We have noticed the amplifier is very sensitive to power.
The other thing was a post from someone with both the Gryphon and the PA 3100HV at the same time in the same system and his response was a bit different, he found them both equal but different, with the Gryphon having a bigger presentation with a bit more slam, however he felt the image was more focused and the treble was smoother with a more tube like sound.with the T+A.
So system matching with loudspeakers and sources are going to push one person to like one of the other.
We heard the Diablo at Axpona and the system didn’t sound that good,

A cheappie T+A R series system was making a lot of magic and that system was a fraction of the price of the Gryphon/Tidal system the other dealer was showing.

Add a set of Critical Mass Center stage footers and a good power cord and conditioner and then see if the T+A doesn’t have a similar slam with the tube like midrange the you get with the HV technology.
As mentioned earlier the OP summed it up it comes down to personal taste.
One reason we were asking Humbetro was if the testing was done in exactly the same way, were power cables used and power conditioning?
It is entirely possible we would have the same conclusion, in our tests the 3100HV has been absolutely amazing sounding and has driven all speakers beautifully.

Please try vitus sia 025. Auditioned both vitus and gryphon
before ending up with vitus. Very close call but decided 
on vitus for its more intimate mids and lousy recordings is
more listenable.
gryphon is much faster, more slam and better dynamics.
