hafler up-grade?

[flingbee]

Hi new to karma. just bought an old hafler dh 200. and have heard there are some up-grades that would vastly improve the performance. where are the up-grades available? How much? How hard is it to do? and last is it worth it? thanks

Check out musical concepts.
A simple recap will get you pretty far, but the musical concepts mods are a big step up.
If you have experience with a soldering iron, that's all you really need.

That and a big wad of cash.

Avionic has a few threads about the Hafler amps. check them out. Or as he said, pull out some serious cash and get the mc upgrades which make it a serious amp. But you will not get your money back when you sell, if you were considering that. dshoaf has posted about his approval of the mc upgrades.

I am replacing my system that i have used for five decades.

tuner, preamp, amp all Sony ES series

I did just pay for a hafler dh 220 + the value of a MC mod. The amp came with the repairs they made amp, in addition to a bench report covering a list of measurements.

I originally planned on replacing with a new Yamaha 710 integrated.

But decided to go with NAD 1000 pre and hafler dh220 MC amp.

I am stunned at the depth of the sound and magical timbre.
For example, I had no idea King Crimson music had so much atmosphere and timber. And that is through a/d/s Braun 400’s.

Very satisfied with this NAD - hafler MC combo. As this amp is overkill for these speakers, im looking forward to completing my resto on my AR3ax’s.

They will gladly suck up the power hafler can deliver.

I’ve been a Hafler guy since the 80’s. My amps were the XL-280, XL-600 with se-100 preamp. I’ve got a 945 preamp, 9120 & 9500 now. Love em. I’ve never tweaked em.

Maybe go through the amp and clean the connections with DeoxIT D100L. As @Sir.Byrd posted, I like the main power supply electrolytic recap option if it’s never been recapped.

I’d prolly use the amp — as is — and see if it meets your needs. You may not need the “parts-cannon” upgrade approach just yet.
