Yes I have a Crack with Speedball. It's really up there in terms of price/performance ratio, but you do need to dedicate some time to build it which may or may not be an option for some people. Luckily, I bought mine prebuilt, but after looking at the manual, it is VERY well written and if you can follow directions it should be no problem. Just take your time and if you ever need help, the bottlehead forums are full of helpful people.

 

Once you get a tube amp though, you open the world of tube rolling which is another monster in itself wink.gif

I've never said the 650 is hard to drive...biggrin.gif

 

The HD650 can be hard to drive, but it's not abnormally so.  It's simply a reactive load.  Most of the headphones you'll find with impedance ratings of < 60Ω are also fairly non-reactive (they're rated at say 32Ω @1kHz but are withing an ohm or two all the way through the spectrum).  There are a few higher impedance headphones that are also relatively non-reactive, but the Sennheisers and higher impedance Beyers tend to have wacky impedance curves (usually having rather drastic increases in impedance in the mid-bass and above 10kHz).  Transformer coupled tube amps will not react well to this.  Amps with SS output stages will react well enough. Though, some will lose power in places.  Most OTL tube amps are significantly less affected by higher impedance or uneven impedance curves making them a common suggestion.  Essentially, OTL amps are easier to predict how they'll sound with headphones like this without looking at their measurements.  For planar headphones or other flat impedance curves (like the Denon D2K/5K/7K's), you don't really need to know how the amp reacts to changes in impedance, but for headphones like the HD650's or Beyer DT880 600Ω's, the sound can be harder to predict without a well matched amp.

With regards to tube Vs solid state, what would i have to spend to outperform my Graham Slee Solo SRG? What do you regard as a 'proper' tube amp?
post #11675 of 19501

Yep Your right of course. 

 

Thanks.

Are there a lot of people here that sold their HD650 and bought them again later on? I'm afraid of getting seller's remorse just to have to pay more for the HD650 again in the future. In my head at the moment I'm just justifying selling them because I'm not using them as much. 

 

I don't know what to do :(

Im getting my pair in the mail tomorrow, excited to see how my CKKIII plays with the 650s.

LOL I am in the same position. 

 

mine are actually for sale, could be a regrettable sale

I'm looking for a portable case for my brand new HD650. I found a case online for the HD555, are the dimensions the same (will it fit the HD650?)?

I imagine the 555 and 650 are similar shapes and sizes but it probably depends on the case. Do you have a link or pic of the case you're looking at?

just received E12, the sound becomes significantly thicker and sub-bass is awesome.

post #11683 of 19501

^^ Interesting impressions. I have not heard the same about the e12. Mostly, I hear thin and neutral. Glad that you're liking it. Are you using the bass boost?

Lets be real here, To power these properly you are looking at an amp that costs as much as the headphones cost themselves. 

 

Anything else isn't going to yeild very good results.

Nonsense. The E9 and Magni does just fine with them. Same with the Asgard 1 or 2.
IMO the DAC has made the most improvement. Strangely the cheapest one I've had sounds the best to my ears.

Also..my Total Airhead drives them just fine. The clipping light never goes on ever and sounds amazing.
It seems a lot of people even love the HD-600/650 off a simple CMOY amp.
