Can someone give a comparison to the valhalla 2??
Yeah I've heard that about the Valhalla as well (detail wise), some have told me that it's good if you're very much into vocals. Been trying to find an inbetween since I had the th-x00's and I thought the playful aspect of the can would mesh with the midrange emphasis on detail the Valhalla gives. this looked like a good deal though so I didn't want to be dumb and pass it up if it was, thanks for your help bud! :D
This is not a good choice for TH-X00 headphones unless you plan to do some mods inside the amp. This amp was not designed for anything less than 300 ohm headphones.
It drives my 32 Ohm SHP9500 just fine, plenty loud and I don't feel like I'm missing any part of the spectrum.
Well, regardless whether you feel like you can hear the full spectrum or not, the math says the cutoff frequency for -3dB point is something like 165Hz for 32ohm headphones.
So, is it cut-off or -3db? My guess is there's just not too much information below 100Hz that you can hear well in open back cans.
So I did more A/B listening vs the O2 and yes I could feel the bass goes a bit deeper there on some tracks that have it. At the same time I also observed some bass roll-off when using the DV as pre-amp, so some low frequency loss can be due to the stock tube. All in all it still sounds pretty good with 32 Ohm in my opinion. I may experiment with the output caps or just get the high impedance headphones in the future, but I think I can gain more with tube rolling initially.
