IMO, the audiophile needs to be well versed in the sounds of different kit, and make a choice based on that, as well as their budget. There are few 'bad' choices in audio, but many less than optimal choices.

if they are are not "differentiable" in a dbt, what possible "meaningful" difference could there be? assuming you aren't driving a decice out of of spec?

"voicing" or "house sound" would be very easily seen on a frequency response graph... VERY easily...

only "audiophiles" are "well versed" in "the sounds of different kit"... others realize that auditory memory is fleeting, and that being "well versed" in the "sounds of different kit" is merely being well versed in marketing literature and hopeful fairy tales...

yes, there are less than optimal choices... however, you aren't hitting upon why those choices may be less than optimal...

dio do you mean that because our ears can only hear certain decibels that we won't be able to notice the differences? like bass that our ears can't hear but feel?

I hope it was just a typo and not what you really want to say.

Aesthetics may not be so enjoyable but fortunately, most setups have them hidden behind the equipments.

No, certain frequencies. Plus, the variation down to certain decibel, beyond which is too small of a variation even for people with very healthy hearing to discern.

This and many other similar variations in perception of sound and music are described in This Is Your Brain On Music By Daniel Letvin. http://www.amazon.com/This-Your-Brain-Music-Obsession/dp/0452288525

Just scanning the AVS forums on a sleepless night and came across this thread......The same conversations are ongoing currently on several audio-centric FaceBook pages......

Not much of a point to this

Hafler was bought out almost 30 years ago so if you have one of their amps, time to recap your amp. It would be unfair to Hafler to put it on a test bench compared to a new amplifier. Heard and played with a Hafler back in the day, went with Soundcraftsmen for their metering. 25 years ago, picked up a Hafler 4 channel car amp, it worked well and created quite the stir. The kids didn't know what a Hafler was and told me I should of purchased a Rockford. The older audiophile folks loved my Hafler as it was better than a Rockford.

As you know, the Hafler was made by Rockford which taught me to avoid letting sound people see what brands I use.

Hafler was a good amp, I never viewed it to be supernatural but they were very reliable.

Part of the reason i went through this thread is because i currently have a 37yo Hafler 500 that i would like to do the necessary maintainance done on. The conundrum i'm having is that my 500 is an early production model with the original design driver boards. I'm trying to decide if i want to update those, get a set of the revised boards that were used in the majority of the DH500's run and renew those or go with other options... I know of the driver boards by Van Alstine and Musical Concepts, but by going that route would be much more expensive and the amp would cease to be a Hafler....was looking at this old thread trying to get ideas...

Old amps,

I had a 25 year old Carver M1.5t amp and it blew a channel. The cost to refurb and make all the adjustments/upgrades was around 400 bucks. Thought about it for awhile, removed the nostalgia goggles, pronounced it dead and moved on. Removed the aluminum front plate and have it hanging on the wall as memories of amps past.

Refurbing an old Hafler, the answer can only be provided by you! Hope it works out for you.
