Just wanted to mention a weird "feature" of this amp with stock tubes. On lower impedance/higher sensitivity headphones it seems to remove bass, but on less sensitive, slightly higher impedance headphones, like my ancient Philips SHP895's, it actually adds bass, compared to a SS amp. Maybe it has a higher output impedance?   I haven't picked up those 6688's I mentioned yet, but my dad found a huge box (rubbermaid tote) of old NOS tubes in the attic. Crossing my fingers...
I actually found this place near me. They supposedly have 3.5 million tubes in stock, over 2000 different types, in a 7500sq. ft. warehouse. I emailed them, and they have Amperex 6688 JAN, for $7 each. I will be picking up a few on Friday. http://www.thetubecenter.com/contact_thetubecenter.html
Just got this little amp, and I'm already amazed!   I've always had a "problem" with my ears, where either mine are more sensitive than everyone else, or they are about 10x more sensitive to sibilance, and "beaming" mids than most people. To the point that there is a physical reaction in my ears (mostly the left) to sibilant peaks. This amp might be the holy grail, in my case. I have been listening to my most sibilance prone headphones, and some known-sibilant songs....
After hearing a sound demo of the t50rp mk3's on z reviews YouTube channel i was floored. I could even hear the airyness, and ambience that they produced compared to something like the hd600, demoed on the same yt Channel. After looking at a frequency graph though, there is a crazy peak around 10khz. Like, a Beyer killing peak. I've read that a peak there is desirable, but every headphone ive ever listened to with one in that area has been harsh to me to the point I...
Sorry for not reading all 9 pages, but just in case it wasn't mentioned, The M560 are apparently "convertible" headphones. They have magnetic cups, and can be converted from closed to open. Still not worth $199 to be the guinea pig, though.
It makes sense that they might be running themselves a bit thin, in order to stay afloat. You are right, I'm sure their entry level "walkman grade" headphones don't use the titanium drivers. They also had an older model of 'behind-the-ear' sport headphones that sounded like garbage. But the Pro4 series apparently use the same titanium driver, despite reportedly sounding pretty bad. I totally agree, that if they put some research into a HD6xx caliber headphone, they might...
Thanks for the suggestion, but I've found that headphones of that design just do not work for me. With the flat earpad, and "mesh" in the center, the driver is just too close to my ear. It causes everything to sound harsh to my ears. I already have a  pair of HD228's, and they are absolutely unlistenable. Every shh, and chhh, sounds like nails to my ears.
Well, my first pair of (defective) UR55's were from a 3rd party seller, but shipped by Amazon Prime (Fullfillment by Amazon). I made sure the replacement pair was "sold and shipped" by Amazon, and they were good. I believe my SportaPro's were also 3rd party Amazon fulfillment, and they were fine. The fitment was definitely not a "fake" issue. They wear small, but I have found tilting them back on the head by about 4-6", so they're resting on the flatter part of the top of...
I didn't catch that part about Amazon. Actually, now that I think back, my very first pair from Amazon came in defective, but may have been fake. They played like they were halfway unplugged. They sounded like an 8-bit mp3, with no bass and an echo to everything, until I squeezed the little "Y" in the middle of the wire. The replacements sounded GREAT, but, over time, the wires have started pulling out of both earcups, so I bought a new pair. It sounds like your source is...
Unless you're in public, try sliding the headband further back (past the highest point) on your head, and then tightening the headband. They look funny, but work just fine that way. The drivers aren't angled, as far as I know, so it won't have an effect on sound, either. My experience has been the complete opposite. The UR55's are the "Holy Grail" for me, in terms of a neutral, laid-back, but also fun headphone, with punchy bass. Those, and my HD203's, are virtually the...
