REVIEW: Head-direct.com HiFiMan EF2 tube Hybrid Amp with USB DAC - Page 88

post #1306 of 1318

How would this amp pair up with the Beyerdynamic DT880's? (250ohm)

post #1307 of 1318
Hey well I don't know about the dt880s, but regarding to questions of this amp/hd600,

The provides enough volume and the tonal balance is great, bit I did have some nos tubes that I have already forgotten what they were rolled in. what it lacks is the dynamics and soundstage. It is those more technical points that gives the ef2's ptice tag away imo.

Does anyone know how this would compare to the Indeed G3 or MK2 ebay amps?

Wish I could help you guys, but we'll need to see who has experience with those.

Did anyone finally get a chance to measure the EF2A's output impedance? I apologize if this has already been answered but I could not find anything in a search of the thread. Thanks

Reviving an old gem of a thread. One of my old trusty Mullard tubes finally gave up recently, having been used pretty much 24/7 for I don't know how many years.

Today these little beauties arrived. Figured I'd give Raytheon a go this time around, and I must say so far they're sounding great. Only expecting them to kick more ass as time passes.

The packaging looks absolutely great....What was your source for the tubes and their cost? I have heard that the raytheons are a touch expensive

Aye, and the exterior packaging was great as well. Also didn't take that long to get here at all (from U.S. to Sweden). I believe I payed about $44 including shipping, and I bought them from this excellent eBay vendor http://www.ebay.com/usr/vivatubescom

No worries mate. I highly recommend them. I loved my Mullards, but the Raytheons actually seem to be a notch above them.

Would this amp be able to drive say HE-400 effortlessly? I thought this was made He-400 but realized this was created way earlier than HE-400. :p

I don't have HE-400 (I have all the others).  It's under-powered for my original HE-5, but better with my HE-5LE and HE-500.  But I can't try to guess about the HE-400. It's fine with HE-500 and HD600 too, although I haven't tried that combo in a while.

 

For inefficient headphones I prefer the EF5 amp, but with something like the HD800 or Grado HF-2 the EF2 amp will surprise you. It's my top recommendation for a budget/cheap DAC/amp for HD800 while someone recovers from Sennheiser sticker shock and doesn't have the cash for a HD800 quality DAC/amp yet.

It's a great review. I much appreciate it!

 

With little knowledge on amps/dacs, I think it's better to start with something not so expensive. So I am considering buying a Hifiman  EF-2A for my HD650.

 

Do you guys think it will be a good staring point? Will EF-2A be a good fit for my HD650? Or do you have other rigs to recommend?

 

Thanks a lot!
