Dear Rives: IMHO if one amplifier is better than other with a specific speaker has to be/see ( between other things ) how good that amplifier match the speaker electrical impedance and for other way what the person is looking for: just sound or music.
I never had the opportunity to hear the Dgob system but I have almost clear what he are looking for ( music priorities ) and something that he wants to achieve is to be nearest to the recording.
I really like the Talons, as a fact time ago I recomended to Dgob stay with it and not change it.
Now and returning on subject as good as the VAC amplifiers are IMHO and due to its high output impedance anything that we hear/heard through it and the Talons will be " heavy colored sound " very far from what is in the recording, you can like it ( like you did/do and I respect that. ) or not but the fact is that that amplifiers can't be a good match ( for music ) not only to the Hawks but to other speakers.
In the other hand the 23.5 that own Dgob is a lot better match than the VACs.
Another subject that you have to know is that the 23.5 ( that own Dgob ) is a unique ML amplifier that has a very nice and unique up-grade that puts it in other quality performance level and IMHO above the VACs, the 23.5 give to Dgob music and music nearest to the recording with a lot lesser " distotions/colorations/noises/etc/etc " than the VACS.
Maybe I wrong but we can't change the Ohm's Law about impedance matching between the amp and speaker.
Now, mi opinion is only that just one more opinion, the important opinion is what Dgob thinks.
Regards and enjoy the music.
Raul.
