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.
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?
