Yes, I am still going through the Denon amp.  I have yet to use the Lyr preamp in low gain mode as some have suggested to increase the sound quality. Also, I bought the Lyr 2 and used it with the trusty little Pico DAC with a moderate increase in sound quality, it wasn't until I got the Bitfrost...

If you are on the fence about buying a Lyr 2, the preamp function is definitely something to take into consideration.  I have a set of monitor audio Silver 6 speakers with 120 RMS watts per speaker and 91 db sensitivity powered by a Denon 1910 receiver with 90 watts RMS/channel.  Yes a modest...

Bump, this is an android device but when I hook it up to my computer, it is not recognized by the Spotify interface.

Does anyone know if the DX50 is capable of playing Spotify files?

Mine do have the gold pins and diamonds as well and like a poster said previously, they appear to be improving, at least up to the 200+ hrs i've had them.  The last things to improve were the bass and sound stage, I'm so happy with them I have stopped the burn in process. 

I ordered my pair of NOS Telefunken E88CC from Upscale Audio one month ago and the size looks identical to yours.  I burned them in for 200 hours and they sound great, if you can't tell a difference in the sound just listen to the music and enjoy.

Ooops

So my stock GE tubes finally opened up and wow.  This is my first experience with an amp that uses tubes and they really make my HD600s come alive and soon two new sets of tubes are coming my way, can't wait to hear the difference.  With a solid state amp the music comes form an X,Y axes, with...

Just for the record, I broke the Dunu through a careless act.  I dropped a heavy item with them in my hand, they got tangles and came apart.  I do not think they are less well made than any other IEM of their type. 

Hey folks, I came across this post on a for sale forum   "I HAVE A 11X33 STORAGE IN XXXXXXXXXX FULL TO THE CEILING WITH VACUUM TUBES (20,000+), ANTIQUE RADIOS, HAM RADIOS,TEST EQUIPMENT, VINTAGE HI-FI AUDIO, ANTIQUE AND VINTAGE CAMERA EQUIPMENT, HIGH END SPEAKERS, RADIO PARTS, AND MORE. I WAS...

The soldering I'm fine with it's taking these things apart that scares me. 

Through an unfortunate event the wire of my Dunu 1K pulled away from the housing.  Does anyone know know how I can get these repaired?

It's here! Placed the order at night on the 24th and it is here on the 27th, pretty fast.  Now to decide on some new tubes for my senns

I've been using the DN1000 with the DX50 but was a little disappointed with the bass, there was a lack of tightness and texture.  My first IEM was the Atrios thus I was spoiled by that wonderful sounding bass.  Anyway, I hooked the DN1000's to a desk top amp and now the bass is much tighter and...

Sounds like a great pair of tubes Jamato.  I just bout the Lyr 2, which is my first amp with tubes, can you or anyone suggest a good set of tubes for HD600, something that will liven them up and bring out some bass? I like to hear bass texture, and real sounding music with a great sound stage...
