I just finished my turkey dinner- very good & lots to be thankful for. I agree with Garland that you might want to check your source- it might benefit from better caps or whatever more than the speakers. Many basic cdp's have the sound you describe. I use a Njoe Tjoeb with a lot of mods to it for cd's, and it sounds smooth, and I listen to vinyl a lot, all through 2A3's, so it's all very smoooooth. haha. Sometimes a good speaker just reveals things from on down the line. Still, whatever gets you to the total sound you enjoy is good. Happy Holidays to everyone!!

My two cents: The resistor idea sounds like the most logical idea and actually directly addresses the problem expressed. Now I'm not entirely sure what this does to impedance, but it raises it. My Technics have a 10ohm Woofer and 8ohm mids and tweeters, and they are still rated at 8ohm. I don't see a big deal with going from 8 ohms to 9 on one driver.

I'd also like to add that this is a "company" supported sub-forum and I really don't like to chime in when the designers would have so much more detailed info and expertise than me, so anything I say should be taken with a grain of salt and is generalized.

It's also the least expensive solution, because a 10 watt resistor costs about $1.25. Get a couple of one ohm resistors and a couple of 1.5 ohms and try both.

Thanks everyone for the discussion. Just want to reiterate how wonderful I think the speakers perform.

My sources are the following: AR XA turntable with Jico SAS stylus on a M91ed cartridge, several Sony' cd players from the 80's and 90's, ipod, iphone, air tunes etc. and I also have a small home recording studio and I use Apogee DAC's and ADC's, which are some of the industry's best.

One of the reasons I am most suspicious of the Solen caps is that I have tried them before. I have recapped some other speakers with them and gave them hundreds and hundreds of hours. One pair of Sansui SP1700's that sound pretty darn good, I eventually changed one of them back to electrolytics (new of course) and compared them directly to the Solen, and Dayton I might add, for months and and ended up taking the Solens out for the tweeters and 4" mid drivers and used the electrolytics.

I still think I am going to just try a pair of motor runs first before altering anything else.

By the way, one of my favorite new pressings to compare left and right channels is the new Beatles Mono Box Set. Since you are getting the exact same mix in left and right, you can get an excellent comparison of sonics and performance between channels.

UPDATE WITH CURE

I cured my problem of high end harshness. I also had a couple of other audio nuts come over to listen and see if they heard it too.

An oil filled motor run cap was exactly what was needed.

When I was trying caps I would try just a single different one in a single cabinet, put on something from my Beatles Mono box set and listen back and forth for any change.

I heard a distinct change when I put in the oil filled motor run. I then installed the other and I could definitely hear a difference.

I have now lived with it for almost two months and I am so happy. All the detail is there with none of the ear fatigue. My friends who came over again to listen to the change were adamant that there was a definite improvement. One said he could hear a big difference on all types of cymbals.

I am very happy. Thanks for the suggestions. I Can't wait to build some 4pi and maybe some type of towers.

What size motor run cap are you using and were did you purchase them. I would like to try the same thing.

Thanks,
Robert

10uf, 370vAC just picked some up from a local electronics store that has tons of older stuff and new stuff.
