Correct. 115 V for North America.
The lyr is a very good amp and pairs well with the 650...very well. But consider that the lyr runs $475 shipped and you MuST roll in a decent set of tubes that will go about $50, so $525. If you are willing to build the crack kit or have someone build it for you, you can get a better pairing for less. Kit =$300 shipped plus the Tung sol 5998 will run about $375. That's an amazing deal when you consider the places it will take the 650.
Both amps are very good choices and my two personal favorites.
The lyr is built like a tank with no maintanence required and has the option to roll in some nice tubes to flavor the sound to your liking. The lyr will also do a great job with other hp's especially planar mags.
The Crack is special though and seems like it may have been build exclusively for the 650. IMO it is a clearly and appreciable better choice for the 650. But it will not have the flexibility to drive other hp's, especially planar mags, like the lyr.
At first, I actually wanted to try the BHC, but knowing that it mainly just shined with Senns and Beyers , I thought the price was a tad to high, unless you build it yourself.
Then I found that the Mad Ear , with the right tube was just beautiful with the HD650.
If you are willing to spend 800 on amp and dac.....you can prolly awing a crack and just be done with it.....then spend the rest on a dac.
Correct, 115v is for NA and 220v for EU, no worries
I can't go into a full explanation. The Valhalla is not bright or sparkly (unless that's on the recording) and it does not act as a tone control. Also, particularly with minor mods and good cables, the HD650 roll off is less than reputed. But what it does in the treble on my HD650s was distinctly more accurate and pleasureable than on the Fireflies and even the Lyr (cables might have made a difference, but all were good aftermarket ones.) Power specs are of limited use, so long as they are not drastically short of phone recommendations. And I didn't say anything about "limits" the naturalness. But I did compare the triode and single-ended aspects of sound to power amps with those features: triodes are smooth and uncanny in their realism with realistic transients but some is illusion due to a bit higher harmonic distortion perhaps. Single ended similarly increases the even order harmonics which are shown in studies to increase perceived realism. On some music passages, this can reduce the vividness compared to, say, the literal but sometimes exaggerated sharpness of solid state, for example. I'm sure others can put these better into words or context than my tired brain at the moment.
Headphonia made mention of the treble of the Valhalla:
"The Valhalla actually had a clearer sound with more sparkle in the low treble. It had a more solid state-like clarity and sparkle, but it’s not exactly dry sounding. It actually reminds me a lot of the sparkly treble in the Grace m902 amplifier section, which is a chip-based solid state headphone amp (I know, it’s totally unrelated, chip amps and tube amps). But I definitely won’t describe the Valhalla as having the traditional “tubey” sound. The Lyr has a thick lower mid-upper bass area, which progresses to a fairly lean treble section."
There was something similar in the 6moons review. I think everything that you said is spot on theory wise and was very helpful. I made mention of the treble characteristics as it is what swayed me in the direction of the Valhalla (650 and Valhalla sitting in a tree m-a-t-i-n-g). I hope I made the right choice and I will get mine tomorrow and see for myself. I appreciate the time you took to answer my question and it reinforced some things I knew and added perspective.
Mine should arrive tomorrow as well.
I bought a Darkvoice 336 a couple weeks ago and Beyer DT-800s just before that (600 ohm). I really love their air, but the upper-mids and treble grate on me with some music, so I'm going to give the 650s a try.
Convenient that I have a nice amp for it, although the RCA tubes I have in right now are probably going to make everything way too warm. We'll see tomorrow!
This is directed to those of you that use a tube amp, I have an Ember amp. I have rolled many tubes and really like most of them. Always felt this amp was a good value. Reading on a high end audio forum, they were discussing using a product called deoxit. http://store.caig.com/s.nl/sc.2/category.188/.f .... I purchased a "survival kit" that had several of their products and info on their other products. When the kit arrived I cleaned all the male connections going back to the pc and the power supply for the amp. I also sprayed the deoxit on the pins of one of my tubes. It was obvious the amount of crude "corrsion" that came off the tube pins. Waited the two minutes for the deoxit to clean and seal the pins, wiped it off and reinserted the tube in the amp. Now I am at a lose. I swear I can hear a little more detail in the upper registers, and the music "seems" a little more open. Tried it on another tube this morning and the same results. Just wondered if any of you had tried this or not, and if so what your conclusions were.
It does sound like a good idea to clean up NOS tubes that have oxidized pins, usual problems being static noise or other random artifacts. The simple act of removing and reinserting the tube will usually clean up the contact but i have heard deoxit can help stop that problem from reoccurring. I should really buy some and try it..
