I'm depressed, my system hurts my ears.Please help

I've been enjoying my stereo for quite some time now, but my latest component addition is hurting my ears. My system is as follows:

Music Hall CD25 CD player
McIntosh MC2105 amp (30 year old amp)
Joseph Audio RM22si signatures
Signal Cable Analog 2 interconnects
Kimber 4TC biwired speaker cable
Denon AVR1700 HT receiver as preamp

With the Denon the system sounded pretty good, but it was the obvious weak link, and was actually performing its own unnecessary A to D to A conversion). I swapped the Denon for a Creek OBH12 passive. I added the Creek because in my careful, volume leveled comparisons of the Denon compared to no pre at all, no pre was much cleaner and more natural (I an use no pre because amp has volume knobs).

So I put in the Creek passive to keep that clarity along with switching and an easy volume control, but now I can't sit in the sweet spot of my speakers and listen, because my ears start to hurt at volume levels that used to be just fine. Is this clipping due to an impedance matching problem? Is this just me receiving the full spectrum of the sound and my ears can't handle it? I remember having a similar problem with a very nice car stereo I installed, it sounded very good but always hurt my ears compared to my worse sounding older car stereo.

I almost wish I had never started down the audiophile path, this is depressing. It's tough to do swapping style comparisons because once my ears start hurting, any music will make them hurt until they have a chance to recover. Any suggestions would be most appreciated.

matt, your creek could well be just allowing you to hear your CD player for the first time. CD players are notorious for producing unpleasant upper midrange glare etc. Thats one reason why so many folks prefer tubes in their players or preamps. I am also suspect of the Kimber cable, i've always found Kimber to be on the bright side. But before you start spending a lot of bucks i would try playing with the toe in of your speakers. Many speakers sound too bright if pointed straight at you. If they are pointed straight ahead you could have excessive wall reflections. Using your head a a 0 degree starting point i would rotate them up to 25 degrees in both directions. I ended up with mine crossed in front of the listening position when i did this.

I wrestled with a similar problem when I owned Avalon speakers. I felt exactly the same despair about the whole audiophile thing--why did I do this? I thought something was wrong with my hearing, had hearing tests, read a lot of stuff on the Internet, etc. For whatever reason, that problem seems to have largely disappeared, though so have the Avalons.

There are certain frequencies that seem to overload my ears with many systems and even with live music. Vibes, for example, and classical soprano vocals. (I think it all dates back to the drum solo during a free Poco concert in Washington D.C. in 1970, but that's another story.) In any event, my advice is to be patient, remove the pre-amp for a while to get relief, then put it back in a few weeks from now and see if your ears still hurt. Experiment gradually, don't panic, and don't be discouraged.

There is another cheap solution to acquire Musical Fidelity X10 tube buffer for your CD-player. Despite adding extra pair of interconnects this unit realy brings lifeless digital components with CDs together to the life.

I believe in your situation you simply experience "digital sickness syndrom" that I used to have not a long while ago thus transfered my collection almost entirely to vinyl. As to this X10 unit it realy brings digital playback to life since I heard in ensemble with vintage NAD CD-player.

It is well known that re-locking errors, lack of resolution brings very unpleasant audiable waveforms onto the wide-band amplification components that can affect upper mid-range, high freequencies and even but not to the significant level bass. Your new passive Creek tend to reveal everything good and bad so the solution is to improve the source at first.

Also you can try to get high quality DAC such as Bel Canto DAC1 that can also someway cure DSS.

As to my digital setup I have a very good transport with relatively mediocre DAC. It doesn't produce any fatigue freequencies to me but I admit sounds cold. For now I only care about analogue and digital setup will probably be for the separate system(bedroom).

My guess is Subaruguru is on the right track. I hope this condition is system dependant?

It sounds like flutter echo to me. All sounds good, other than a shoutiness (ie. it sounds like mid-range performers and instruments are shouting at you). If you can put the system in another room for a day?

Otherwise, set the system up for nearfield listening for a day. That is, with speakers well away from all walls and you sitting very close. Then see if your ears still hurt.

If this seems to cure the problem then flutter echo is probably the cause. This occurs when you have two relectivs room surfaces in parallel. The simplest cure can be moving from firing the system down the long side of the room, to firing it across the room at you. Otherwise the issues are as discussed above concerning dampening reflections and careful speaker placement and listening position.
