jwm841 posts05-13-2017 9:21pmGeorge I would put the Rockport’s along with your Wilson and B & W speakers. Depends which model and if it had a test/s done so we can see the impedance vs -phase angle graph then I could answer that for you. This old model " Antares" had a 3ohm load at 200hz and 4-5khz which isn’t bad seeing there is no nasty -phase angle at those frequencies as well. So both amps should work well with these speakers, the Ago having slightly the better drive/punch though at 200hz. The Ago will definitely sound better at 20hz with pipe organ. because at 20hz there is 4ohm and -50 degrees which is a current sucker from an amp. Also Sprach Zarathustra (2001 Space Odyssey) has a 20hz organ at the begining. http://www.stereophile.com/images/archivesart/rokantfig1.jpg Cheers George |
I've heard all the D'agostino amps in my system as well as the Dart 108 and the MXR-20s. The D'ags got my vote but there is something special about the sound of the Dartzeel. Listening to the 458s is high on my list but I have to make sure I have the coin ready to flip should I find them inexplicably irresistible. |
Thanks for the responses folks........I ended up getting the Dag, and it's pretty hard to fault. Obviously a great amp which is very responsive to the gear around it. I found it to be fantastic with Purist power cords and a tube preamp. JTinn.......I'm running Tannoy at 96db so yes I think the Dart would have also been a good pick, although the Tannoy do love the iron clad grip the Dag has on them. |
I’m interested in the NHB-108B. I’m also very interested to see that they illicit a $130,000 pair to make a comparison. Apples and oranges I would think, but interesting. For my mastering studio I’m looking for lower power, as I sit 7’ away in a controlled room (mastering) and the NHB-108 B would be replacing tube amps, highly modified Class A Push Pull Cary 211 FE. The pre amp is solid state and very, very good, Crane Song Avocet - balanced out. Speakers are Allegra by Joachim Gerhard, with external passive crossovers done by Jeff Glowacki @ Soniccraft. Bricasti M1 SE DA. Thoughts on the 108 B in this setting anyone?? Thank you |
