Yes, I bought a set of HD668Bs around a year ago from you. They are a great value! I really enjoy their sound signature. It is a lot of phone for the money. Very comfortable, very durable, nice accessories. Not very sealed, though. That would be my only complaint, albeit minor.   I hope your...

I just bought the 271 Mk II off amazon (via adorama). I paid $149, but when I received the HPs the label said "Made in China" on it. Build quality still seems good. They are very comfortable, but they can get a little warm after a while. Isolation is very good IMO.   Great sounding HP...

I opted for the AKG 271 MK II. I found a great deal on them at Adorama.com. I hope they are legit, and not fakes.   BTW, other than crap sound (which many cans have before burning), what's the tell-tale sign of fakes? A reviewer on Amazon posted pics of some AKGs w/o the 'Made in Austria"...

I'll definitely give them a listen. Best Buy is the only we have around here anymore, and they mostly carry overpriced crap from Bose or cheap IEM. I'll see if my local store carries them. Thanks

Quote:   Yeah, you sell them. Nice try.   A few days ago, I ordered a set of Superlux HD-668B from a company called AudioHipster (also located in GA) which is suspiciously similar to the above poster.

Are any of the Koss cans any good (other than the Porta Pro, which is open)?   e.g. Koss Pro4AAT Titanium

Quote: Well that eliminates that one. Thanks (I'll edit it out.)

I have considered that one. Others I am considering are:   AKG 271 MK II, 240 MK II A-T ATH-700, ATH-ES7, ATH-M50 Senn HD448 Beyer DT 440, DT 770 Pro Denon D1000 JVC HARX900

A few points for consideration:   I like my Grado SR80s, but I need a set to listen to in bed while my wife snoozes next to me.   The Grados are a tad bit harsh on the top even with the EF2 tube amp. I'd like something with a bigger soundstage (wider and deeper), as well as better...

I have the SR80, and I picked up a Hifiman EF2 a while back. Took a tube roll and then some burn-in time, but it now sounds fantastic! The EF2 took the bite off the top end of the Grados. There may be better options out there, but for around $170 shipped you can't go wrong with this, IMHO. Lots...

That sounds like a good plan. The comparison over at headfonia put this Audinst on the radar. I had previously considered the uDAC, but now I think I might drop a little more coin and pick up one of these Audinst.   Thanks for your input.

Any idea how this would mate as a DAC to my EF2? Would it render the EF2 unecessary?

Quote: Yeah, the SR80 was pretty harsh before I rolled the tubes on the EF2. Now that the CV4010s have around 100ish hours on them they have smoothed out the top a bit. Really nice, articulate low end, too.   The 325i constistently rates as the one of the 'best' headphones out there...

I have the Hifiman EF2 (w/ tubles rolled to Mullard CV4010s). I use it with my SR 80s, and it sounds fantastic late at night when everything is nice and quiet. Can't say they are the greatest rock cans, though. The 80s are definitely worth the few more $$ over the 60s, IMHO. The bass has more...

The 325(i)s continually rack up the awards regardless of price category. I would take a listen to them is you get a chance - listen to everything if you get the chance. I have the SR80s (about 6 yrs old now), and they sound amazing with my EF2. That brings up another point: don't blow all your...

Also, any recommendations on a bang-for-your-buck interconnect to mate the uDAC to the EF2?

I've been thinking of a headphone move lately, but I can't find anyone around town that sells higher end phones. I love my Grados, but I'd like to get some ambient noise reduction and A LOT more comfort for longer listening sessions. Denon and Sennheiser are the most enticing brands right now.

Thanks HeadphoneAddict for your great review (and product support). You really should be getting a piece of the Hifiman action for all your hard work. What's the weak point in my system...err, next area to improve (other than my ears and music collection)? Phones? DAC? Tubes? Cryo cables...

I'm a relative newb so I don't have a wide variety of experience with gear and specs. You may want to read two excellent reviews on here that have a ton of info on the two amps. Pencham did one (w/extensive coverage of tube rolling) for the LD, and Headphoneaddict covered the EF2 very well...
