Hafler DH-100 - what should this should this sound like?


I have never heard a perfect example of one of these so I no idea what the target is here.  I have a DH-100 that i completely recapped and replaced all the OP-AMPS, JFETs, Regulators, diodes, etc.  I more or less replaced everything except the resistors and the pots.  I have tested it and it has exaggerated bass and sounds a bit muffled to me.  However, it is totally quiet;  with no inputs, I can run it into my 75 watt amp (Speakercraft BB275) all the way up and there is no noise at all.  The phono section will pickup the 60 cycle transformer hum but connecting a TT with a ground makes that go away, too.  I've been thinking there is something wrong but I can't find anything.  I have even checked all the resistors and found them to be in spec.  I have run my amp through the "record" output and the heavy bottom muffled sound goes away.  I do like the less than perfect "fat" sound but I have to run this with the bass backed off most the way to make it listenable and I normally bump the bass up a touch on other devices. What should this thing sound like?

I owned one a long ago with a B&K 200 watt amp, KEF bookshelf speakers and a sub-woofer. It never sounded bass heavy or muffled. If I had to remember how it sounded, I would say neutral tending toward bright, as the sound through the B&K was on the warm side and that amp was very warm sounding. 
wow so this is going back 30-35 years now... i had a dh101 to dh200 combo -- my recollection is that the combo was a neutral sounding pair, not thin nor fat in the mids, quite clear and open, a little soft in the bass, slight treble grain/hash/sizzle... but very very good for the money
Thanks for the input.  For what I'm going for this should work perfectly then.  I'm certainly not a professional electronic tech, barely even an amature one, but thanks to your input I know there is gold at the end of the rainbow.  I will keep trying to figure this out.  Thanks again.  
Neutral sound. Do you think the problem might be in the tone control section which I believe is bypassed the record output?  Try Deoxit spray on the pots, look for an out of spec component in the tone control section.
