REVIEW: Head-direct.com HiFiMan EF2 tube Hybrid Amp with USB DAC - Page 4

Definitely the latter

Plus, I bought 4 of the Raytheons to get a better price, so I had 2 spares

thanks a lot for the response, i was considering the d10 and pico but this is enough for me to place the order for the EF2 instead

i will keep my d2 boa until the ef2 comes for comparison's purposes.. i cant wait


one quick last question:

if i wanted to upgrade the tubes in the future, how hard is that to do? is it a plug and play type of thing or does it require tools/experience?

thanks

Good to hear, thanks again for the review, can't wait to receive mine!

Thanks HeadphoneAddict and Skylab for the tube rolling info, that's very helpful for a newbie like me.

Now I'm happily waiting for my EF2 to arrive!

I could resist no longer. Payment has been sent. Awwwwww yeah.

I'm going to take my time and read more on tubes before I go buy some. I should have plenty of time while burning in and trying out the stock tubes.

i felt the same way i too am going to start reading up on tubes, this is my first tube amp! albeit a hybrid


btw, people like skylab, headphoneaddict, etc should be receiving commission lol i'm sure many people purchase products based on these detailed reviews !

Great job Larry as always. Nice to see that you've gone to the extent of comparing it with Amphora and others. Sure seems to be another hit from Head-Direct.

I would like to thank both HeadphoneAddict and Skylab for your great reviews.

I just picked up my EF2 that Fang sent me. I have had a busy weekend but I wanted a quick listen so I hooked it up to my 160 Gb iPod Classic using an ALO Wooden Dock and a pair of Silver Sonics BL-1 interconnects made by Moon Audio. The files in the iPod are all Apple Lossless and the quick listen tells me this is a very nice sounding unit. I will have a lot more to say and will post more in the next week or so. Meanwhile I leave you with the following pictures.

At $189 this should be selling like hot cakes!

Just wondering, is the dac 24 bit / 96 khz?

Wow - cool seeing it next to an iPod - that thing is seriously small for a desktop amp with an inbuilt DAC. Impressive - look forward to hearing your thoughts!
