Head-amp questions???
Hi,
I have MbQuart 450Pro dynamic headphones (300 ohm impedance) and I am looking an amplifier (looking about 1,2, i don't know how much years - a very good one) to work with them. These headphones are very good ones (used to monitor final stage of music recording in studios) but they are a little bit closed and like to have a very quick, open, with lots of air arround,spacious and dynamic amplifier.... I have made few amplifiers (some of them qrv07 (PerAnders), some opamp designs with no names, brute force in a line stage (Barbour), some 5687 tube designs,...)but none of them worked best with them (I have allways feeling that they could perform better).
I am currently listening to a qrv-07 from mr. PerAnders using opa134 and TPA6120 opamps (I will try to put OPA627 instead of OPA134). It is o.k. but too clinical and not so spacious. Everything is inside my head (not going arround it - if You know what I mean)........
I have been looking to an Borbely Tube Mosfet Opamp from Designing an Opamp Head-amp article.....Would this be the answer for me?
I would appreciate suggestions - what to do (make) since I am tired of looking..... (yes, i know that this might be painfull road)...
Suggestions what might be the solution would be helpfull - no output transformers please.....
best regards
