Hafler DH-220 performance and modifications

Hello,

I'm looking for feedback from users of this amp and anyone who has performed one of the two modifications that I found:

1. Cordell DH-220C

2. Fantasia (formerly known as Qua-Co) PC-1

I have an old DH-220 that has not been used but a friend tested it and told me it works. So, I can replace the old caps and clean it up and use the original design. Alternatively, I can purchase one of the above modifications (kits for sale on Ebay) and pay around $300 - $400 and work on that.

If you have experience and opinion on the original VS the modified please share your thoughts. I'd like to know if it's worth the labor and time to mess with the DH-220.

 

Thanks!!

I'm not familiar with either of those mods, but have owned a DH220 and DH500.  While both are powerful and stable amps, they're not among the most transparent or musical amps I've owned, so I'd definitely consider pursuing some possible upgrades while you're inside of it. IIRC, years ago I think Musical Concepts and VanAlstine had some well regarded mods for those amps.  

Good luck, and please post an update regardless of which direction you choose.
