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

Yes,they are quite different.Both are excellent amplifiers.The big drawback to the otherwise outstanding XL-600 is the cooling fan.If you would like to talk more on the subject,give me a call.

Hi Transnova

Is it possible to replace the stock Hafler XL600 fan with newer fans that can operate quietly but yet still put out a decent amount of cfm? I like the look of the XL-600 and would opt for that amp.
I'm not sure about replcing the fan.It would solve the problem for me.I have always been aware of the fan when it runs at lower listening levels/during quiet passages.Other than that,I think the XL-600 is one of the greatest amps ever made! It has a big,dynamic,natural sound.Brass sounds like brass,piano sounds like piano.I get much of the same character(w/o the fan)in my current favorite--Muse model 160.
Even though the XL-600 is very powerful,it is not great into tough loads(Like Infinity Kappa 9).The 9505 is much better in this regard.
