I've said it once and I'll say it again, the JDS Labs O2 amp and DAC pair beautifully with the BE's. You won't find a better desktop pairing for the BE's at this price. https://www.jdslabs.com/store/#featured

I've gone through a number of desktop amps over the years, and I've found that the JDS Labs O2 amp and DAC pair beautifully with the BE's. I run USB out of my computer into the DAC, RCA stereo cables from the DAC to the amp, and then plug the BE's right into the amp...

I recently bought a pair of the BE's and went for the "blemished" at only $199 since the new ones were out of stock . . . what good fortune that was. I went over the pair that I received with a fine tooth comb repeatedly and found nothing blemished, they're perfect. 33% off FTW! Sonically, the...

Just wanted to bump this necro thread because I finally found the perfect solution and it sounds surprisingly good.   Pandora One via USB < Schiit Modi < custom O2 amp < Klipsch X11 I'm using the JDS Labs Objective 2 with the following options:  - no batteries, AC power only  - 2.5 & 6.5...

I read issues regarding the original Magni and floor noise when used with IEM's. With the new model equipped with 2 gain options, perhaps that's no longer an issue . . .

  I was seriously considering combining the O2 amp with my Schiit Modi until I realized that it was battery powered. I'm not sure what the long term reliability would be like with the batteries in a state of constant charging. Any thoughts?

Hmm, no suggestions, huh?

I figured out the software issue holding the Fiio E10K back in volume, but it still sounds pretty poor. The mids are muddled and the soundstage is terribly narrow. Frankly, I can't imagine why anyone would recommend this unit. (and I LOVE my Fiio X5, so I'm no Fiio hater) Any suggestions for a...

After spending countless hours researching and a failed experiment with the Fiio E10K, I need some help . . . I'm looking for a desktop amp (or Amp/DAC) that can specifically handle IEM's, in particular the Klipsch S4 and Sony MDR-7550. I tried the Fiio E10K and it sounded muddy and didn't...

I was fortunate enough to audition the PM-2 over Christmas, which meant I also got feedback from my little brother who's graduating in music performance this spring, as well as my father who's a steadfast audiophile. (Legacy Audio Focus SE and Stax SR007 in his collection) We all listened to the...

PM-2 Unit #1 shipped out to the next person last Friday.

PM-2 Unit #1 is due to land at my house today.

  Nope, you signed up right after me. See thread post #67 and #68.

  Sounds great, let me know if you need my address.  

IGNORE THE ABOVE POST!  Although you can fit the S4 tips on the 7550's, I strongly recommend against trying. The tips are a bit too narrow and have to stretch over the nozzle, which decreases both soundstage width and lower frequencies a few db's, and more importantly can become a health hazard...

  I didn't get to spend much time with this yesterday, but the Klipsch tips do indeed fit on the 7550's. I kept the left IEM stock and switched the right IEM to the Klipsch tip, and the increased comfort was almost immediately evident. Within 10 minutes my left ear started to ache as usual, but...

    Tell me about it, the rave reviews about comfort played a big role in me going with them, now I'm kinda pissed. Today I'm going to try pulling the tips off of my S4's and testing them out on these.

I've gotta be honest, after 10 hours on my 7550's I'm very disappointed with the comfort. After only 10 minutes of listening my ears start to ache. On the other hand, I can wear my Klipsch S4's for 8 straight hours with zero discomfort. Any suggestions, guys? 3rd party tips?

Bummer, I had a strong feeling that that would be the case. Thanks for the info!

Has anyone ever recabled a Sony MDR-7550, MDR-EX600, or MDR-EX1000? I have a pair of Sony MDR-7550's that I 'd like to have custom cables made for, but I'm not sure if it can be done. I already reached out to one established custom cable company, but received no response. Perhaps that's due to...

A bit off topic, but has anyone seen a pair of MDR-7550's running custom cables? Or know of a company that has done it?

I'm very interested in trying the PM-2's and agree to the terms and conditions.

I'm not sure if you ended up going with the Klipsch ProMedia 2.1 system, but I finally managed to kill the amp in my system. I suspect it has something to do with running non-factory speakers with the Klipsch amp, but who knows.

I finally scored a pair of Sony MDR-7550, thanks for the suggestions, guys!

I hope the buzz gets works out, I have high hopes for this thing being my office speaker/headphone amp.
