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...
