Hafler XL600 Vs Hafler 9505 Much difference?


Hello all, I am new here and still learning to navigate the website. I have been out of audio for a number of years. I had an old Hafler XL600 years ago and really liked it for the price. I am thinking of getting into audio again and am considering purchasing either an XL600 or the newer Hafler 9505/9500. I have read there have been a lot of improvements in amplifiers in the last decade. Is that true? How much difference is there in the amps I am refering to? Would I notice a difference between the XL600 and the newer amp? I hope to purchase Boston Acoustics VS336 speakers to go with this.
Any info would be helpful.
Thanks

No, I looked at the link and it didn't mean much to me. I live in the Philippines and my biggest challenge at the moment is finding someone who will repair the Amps using my parts. I went to a chain shop yesterday that was recommended but I have to use their parts. Who knows what they would be.
I appreciate your input. I should be hearing back about a different tech recommendation today.
Wish I knew someone competent, and close to you, that I could recommend. If you lived in Indiana; I'd help you myself. In reality; one only need be able to use a screwdriver, to replace the filter capacitors(in the 9505). No soldering involved. Just disassembly/reassembly. It's unfortunate that Rockford has stopped supporting the Hafler line, with replacment parts & service. Hope you get your tunes restored, and soon.
Hi Rodman99999 Got my Amp working. Something in one of the fuses only. I blew out the fuse cases and switched the fuses and it WORKS. Happy camper here.

I had taken it to a store here that was recommended but they insisted I uses their parts. Being in the Philippines I said NO way. :)
KUDOS! It's a good thing, to learn to do repairs on your own. Enjoy your tunes!
Rodman, I take it I could use the FRED bridges in my Acoustat TNT200s also? The 9505 is essentially the TNT circuit. Sonically, what is the improvement?
