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!!

John Hillig of Musical Conceptsdid several levels of DH-220 mods, all were good. They seem to still be in business just west of the city of St. Louis. Some of his mods are more than just parts swap outs.

As a side note, if I recall correctly, a DH-200 and a DH-220 are very similar in design. The -220 just runs at a slightly higher voltage. But I may be wrong. I add this because I think modifications to a DH-200 will likely also work in a -220.
