I inquired to Musical Concepts and it seems to me by the amount of upgrades they have that they have done many on this amp.Check out the web site.Good luck
Hafler DH500 mods
I have a Hafler DH500 amp and although I enjoy it, I feel as though something is missing. I really dont have the money for a new amp but could find a little to modify it. This amp's been around long enough that im sure many of you are familiar with it. Does anyone have any suggestions on some modifications to bring the best out of this tank without braking the bank? I purchased it around 3 years ago on Agon and the seller informed me that some mods had already been done by an MIT guy. (ok) The only thing I have seen inside that points to this is a rectangular cap soldered between the output caps. I need help fellas. Let me know what you all think. By the way, Im using PSB Stratus Goldi's and a Adcom GFP565 preamp and a Sony DVPS9000ES.
