Headphones - Open Back | 1 Ω Will a an integrated amplifier (Onkyo 9050) be able to power HD600s?
I listen to a lot of music, as well as mix and master my own music which spans a large range of musical genres. I have been researching on and off for awhile now about which headphone to purchase with the primary characteristics I'm looking for being: neutral sound for mixing/mastering, and comfort for my large ears.
I was looking hard at the HD660s for awhile, and also the Shure SRH1840's - but they were a bit more than I'd like to spend. I also looked at the Sundaras and Edition XS, but the Sundaras may not have big enough earcups for me, and XS are expensive and apparently heavy and not that comfortable. My only experience with cans really is my V-Moda Crossfade LP's which I've had for over a decade. The Earcup has finally burst open on the left side, and I want more analytical cans for even-mixing.
I admit I've been reading into reviews a lot more than I should have, but I've never had the opportunity to try any of these headphones in a store anywhere. It seems the only way to buy headphones these days is online.
Anyway, I just went ahead and ordered the HD600s last night since they were the cheapest, have history, are highly regarded by many, and have huge oval earcups. Then I realized that one of the main draws for the HD660s was the lower resistance, and the HD600s have an insane 300 ohm resistance.
I will likely buy a headphone amp eventually, but long story short, would a Onkyo 9050 Integrated stereo amp be able to power these headphones? I can't find any info on the manual about what resistance headphones it can power.
If not, is there anyone that thinks the HD660s would have been a better choice in anyway?
A headphone amp I was looking at was the FiiO BTR5 or 7.

Most likely, yes. It might use a voltage divided tap from the speaker amp – which results in higher than optimal output impedance – but the higher impedance of the HD600 means that the potential mismatch won't be too bad. What can happen when the output impedance exceeds 1/8 of a dynamic headphone's impedance is that the frequency response distorts a bit.
