Have you listened to the V200s long enough to offer a comparison?

post #152 of 2440

I listened V200 -15 minutes and V281 - 30 minutes in the same place in Munich,

before Violectric never heard,

there were SPL Phonitor and other.

Xenophon,

 

I have long been looking for an amplifier for my Sennheiser HD 800,

 

I had Eximus DP1, LUXMAN P-1u,

listening to headphones with several tube amplifiers (Leben CS-600),

but the sound v281 liked more than others.

But this is only my personal opinion.

Yeah, at the end of the day it's always personal taste that determines most if not everything.  If I've learned anything in audio then it is that enjoyment is not a science thing.  But thanks for your impressions.  Interesting that you have the big Leben, no issues with hiss with the HD-800?

 

I'm on the fence and have a love/not so perfect thing with the V200.  Depending on my mood and the type of classical music I listen to I prefer a slightly warm-neutral sound or something dead neutral/crisp and airy sounding such as the Antelope Audio.  For the first sound sig. I reach to my tube amp which is a type that sounds very ss-like or for the V200 which is also a little bit warm.  If I like things detailed and a bit more aloof then neither the tube amp nor the V200 will do but my F5 works nicely.  

 

Fwiw I think there's a very good chance the V281 will better the EF-6 with the HE-6 headphones.  Design and soundwise I've never been extremely impressed with the EF-6, feel it's massively overpriced.  Its one quality is power but the V281 should come close.

Yes, you are absolutely right, all a matter of taste,

but for myself, I have chosen  amplifier to my headphones.

More pics - I'm too lazy to copy/paste so I'll just LINK

I have to say I really like that silver front panel!

post #158 of 2440

I hope we dont have to wait much longer to have our amps.

post #159 of 2440

They should be coming really soon. I'll ask Fried about it though.

Almost pulling the trigger on the V281... oh God

Which version are you guys getting? Did anyone already pull the trigger on the 128 stepped attenuator edition?

I just did it. V281, silver plates, USB 24/192, volume control level 2.

My poor wallet...

Finally we managed to measure V220 and V281.
For a better comparison we added the data from V200.
