Hafler 9500 vs Bryston 4bsst Class Rating B vs A

Upgrading to the latest Hafler 9505 is definitely worth it. Great amp and a big improvement over the 9500.

I guess its a matter of perspective. I own the Bryston 4bsst with the bp-20 preamp. I owned a parasound. They are both fine amps but to my ears the Bryston is more neutral with clear highs, great mids and very good bass control. It goes to show you that different ears hear different things

Thanks for quick replys .
A little more about myself and system my hafler is slightly modded by myself .
I too have sold gear in the past but now just repair and watched the amps change over the last 30 years .
I have had a bryston 4b but was old model and was ok but not up to speed .
Really looking for direct comparisons for these 2 amps as I no longer can try anything out just buy .
I just put back together an old Sansui 9090 so many of these (70s rxvrs) are still out there as they were built tough do not run with high bias , but the parts just were not avialable at that time to sound like they do now , for example the matched Fast types used in Bryston and many others .
But as an audiofile my budget is not that high , that is why Bryston looks good to me ,and if ever resell be no problem .

Hafler 9505 slew rate blows away the paltry Bryston. Parasound Halos also have a high rate.

And to my ears the Bryston blows away the hafler.
