This is a photo of my Senn PX100 (the original one), and it was my beater pair of headphones for a while. I used to throw them in my backpack and they went with me everywhere without a word of complaint. Now they are retired and have been put to pasture, except once in a while I saddle them up...

The Martin Logan Mikros 90: A Bridge Too Far It was a dark and stormy night. OK, not really, but I have always wanted to read a review that started this way. And now I have, and so have you. When the Mikros 90 was conceived, it must have been a dark and stormy night indeed at Martin Logan...

This is a review of the Shure SE315 in-ear monitor (IEM). IMO the SE315 is a sleeper. Let me explain.   But first, the obligatory photo.     Strophe   Shure has been quietly refining its IEM design over the last decade, and gaining increasing recognition for ots products. You could argue...

Accidentally Extraordinary 51st Studio Headphones "Accidentally Ordinary"     The Scene: Chili Palmer's office in downtown LA   "Chili, I've got an idea for a movie."   "OK let me have it, Harry."   "Imagine there's this guy who works in the boonies in Utah in education as a teacher...

Drop to impulse speed!   The problem with deals is that you end up buying stuff you never wanted in the first place. So when I saw the Nuforce NE-600X for under $10, I immediately felt that familiar feeling when the two little dudes climbed out of my clavicles and took up their usual places...

>Which would you recommend for female vocals, AKG Q701 or Beyerdynamic DT880?    That's actually a hard question to answer, IMO. To simplify things a little, the human voice ranges from about a F2 to C6 range, which equated to 80-1100 Hz. Of course overtones get higher. When you consider the...

Would You Like To Join The Q Continuum?   Picture of my "Stormtrooper" Q701     But First, a Preface: And Now, The Larch.     The scene: AKG HQ. A bunch of AKG executives are sitting around a table deciding on a strategy to counter the whipping Beats is giving them in the marketplace...

Preliminary impressions of the Fostex HP-A4 DAC/headphone amplifier   or   "The Little Black Box That Could"       Fostex? Who dat?   Fostex has been around for a while. In addition to manufacturing their own products, they OEM for other brands (think Denon headphones, for example)...

the sound gets better over the first 50 or so hours of burn in :-)

looks like mullards :-) enjoy them!

Yep the plate color is black. JRC = RCA. Once the tubes burn in, try swapping them out for the Mullards and decide for yourself if the sound changes, I think Mullards + LD3 = great combination!

According to reviews on the tube rolling thread, the RCAs with black  plates are supposed to be quite good. I did swap them out for Mullard M8100s (CV4010s) and they were a great match for the amp - warm lush midrange, tight dense strong bass, vibrant highs without sibilance. I'm going to run...

What tubes did your Little Dot come with? My Little Dot MkIII had with stock RCA black plate 5654 (6AK5) tubes instead of the GE tubes that seem to be the typical stock tube.    And for the tube gods of HeadFi: Is that a good or a bad thing?
