The reviewer thinks it's (HA160) one of the best amps for AKG 702/701.

AKG 702 review, where the same reviewer reinforced it again in his closing that:
Quote:
| Final comments & suggestions: [AKG 702] Demands top quality amplification with drive and painfully long break-in. Essentially a studio monitor spoon-fed on neutrality and resolution, not an editorializing home hifi design. Properly driven, it is not however a flat, dull, uninvolving sound at all. It simply needs muscular amplification of high caliber. The €499 Burson Audio HA-160 is just perfect. |
I don't know if it's really one of the best amp for 701, but I do have one and all I can say is my 702 sounds great with it.
