Likely culprit for harshness at higher volumes?

Its probably a combined effect of everything together more than due to any one thing.

I'd get some decent ICs as an easy and cheap thing to try as a first step.

I'd recommend a used pair of MIT Terminator 2 or 4 ICs for < $50 used as a first step to help tame things down a bit and get more out of what you have before changing anything else.

Next I'd look at some decent but not expensive speaker wires also for an upgrade. DNM Reson would be my first choice.

From there, perhaps a tube DAC upgrade to use with the CD player or a tube pre-amp if the harshness exists in multiple sources, not just digital.

For a tube DAC to help tame things further, I'd recommend an mhdt Paradisea or even better a mhdt Havana if you can squeeze it.

Is there any adjustments on the pre-amp or amp that might be turned up too much. Isn't it possible to have the inputs too sensitive?

Hi folks,

Again, thanks for the continued expertise and help. BTW, I should mention I'm on a pretty tight budget which explains my rather dated and very modest system as well. :)

Started the experimentation this morning with room dynamics while waiting for Radio Shack to open.

I'm still testing but it seems that room dynamics is having a strong first order effect.

I changed the configuration of the room such that the listening direction is across the narrow of the rectangular room. So, the listening distance may be slightly shorter (not by much -- maybe a few feet at the most) but it allowed wider separation of the speakers. I also put up some fabric to try to minimize reflections.

This change allowed me to increase volume levels from about -20db (when I would start to hear harshness) to about -5db (where it starts to get uncomfortably loud); at this point, I hear a little harshness but it's not nearly as much as before. The harshness is almost (but not quite) acceptable.

Wow!! Just a little grunt work and things seem to be improving. Either that or I need coffee and my ears haven't woken up yet.

I'm still working my way through the 4 steps but so far things seem promising. I'm hoping to make what I have work -- basically have a zero sum budget. If I buy something, I need to sell something else. :)

BTW, a lot of terms, brands, parts (ie - HF glare, congestion, ferrite clamps, etc) you folks mention are new to me. I've been spending a lot of time looking things up on the internet. Thanks -- I'm learning a lot. This has been a good experience -- you've all been very helpful.

Good to always max out the configuration of what you have first via tweaking with placement and room acoustics first before changing anything.

If you can squeeze it somehow, an inexpensive IC upgrade might still do some nice things.

Good luck!

@Mceljo: I set the Front Speakers as Large. I don't have center, surround or subwoofer (probably meaningless, but I set the sub x-over frequency at 160Hz from 80Hz; I feel my speakers put too much weight on bass). Other than that, I set the effects to Stereo (no processing) and have bypassed Tone controls.

Using analog inputs now --- I have them going into the Direct Analog inputs which is supposed to bypass everything except volume and tone (which I've set to bypassed).

Other than that, I'm not sure what to check. Is there something else I should look at in the config that I've missed? Nothing else seems to be mentioned in the manual (that I recall).
