What is the preferred amp dac for this head phone please? My budget is in the 150dollars but if cheaper better. An amp alone without dac ok? A magni 2 only ok? Or the objective 2 amp? A magni 3 maybe? I have the fioo e10k but apparently not good enough to drive this beast!
First of all it’s not a beast. As a matter of fact it only needs a higher voltage because of its high impedance, but it doesn’t need a lot of current at all. It generates about 103db with 1vrms. In fact, any amp that can throw up to 20 or 30mw under 330 ohms will suffice To begin with. My DFR Red portable amp generates only 2 volts and probably no more than 15mw and it suits me fine for portable usage With my HD6xx. All of the amps you mentioned will do it. Another alternative you have not indicated is the Aune X1s now on sale on Massdrop. But seriously all of the O2, Magni/modi, Aune X1s, even the inexpensive NX-1s could do it. Your Fiio e10k would even do the trick with its 7v+ peak to peak available voltage.. The Headphonia site had this to say about that:
« The E10K is still capable of doing 24/96 and puts out 200mW@32Ohm (<1.04Ω). It’s suitable for 16-150Ohm headphones but it can actually even handle the 300Ohm Sennheiser HD650. Of course don’t expect spectacular sound but with the Bass Boost on, it’s quite fun to listen to. The OPA1642 is in charge of the +1/+9dB gain section but I didn’t really need high gain for any of the headphones I tried it with (more in the sound part). »
Evidently the better and the more power the amp can do under the high impendance of the headphone, specially at higher listening levels with a lot of bass transients, the better sound you will get. If I were you, I would strart with the E10k that you already have and updrade only if you find that your listening habits and volume necessitates a higher grade and higher powered amp. Just my 2 cents.
There's a great video on yt for this
Thank you for detailed explanation. I think I will do just as you said. Will try it with the e10k for some time and later upgrade if need be. I will feel the upgrade more then. I was just scared that when headphone arrive, I have to wait some more for dac amp order. But if fioo can drive it ok, I will try it out first. Thanks again.
Cool, will search for it n check it out. Thanks. 😀
Which amp/dac combo should I get? Budget of 200$ max. Should I opt for the Magni Modi 3, Fulla 2 or the O2 Odac?
From what i gathered in this forum n yt. My personal recommendation would be modi 2 magni 3. But if you can wait its better as modi 3 could be coming out. I will be getting those two if my fioo e10 is not good enough. Objective 02 is neutral in sound and magni adds some color to the sound.
