HAFLER UPGRADE! Good or No?

[mona979]

Hello,

I need some feedback. I have a Hafler XL-280 and found a place to do a total upgrade which looks like it will really make a big difference: link for upgrade: http://www.musicaldesign.com/mc_amp_mods.htm

Any feedback? Anyone had this done before? Was it worth it?

Thanks
