Both the HeadRoom Ultra Desktop Amp and the Grace Design M902 are of similar price.

Which of the two would HeadRoom recommend for the HD 650's. Both are on sale there.

This has a good comparison using the hd600's. Stereophile: HeadRoom Desktop D/A headphone amplifier

Oh geez, thanks mang, I needed a good chuckle. What do you think I'm gonna say?

How about this: I know folks who own the Grace and like it a lot, the fact we sell it says a lot.

I'd take the Ultra Desktop in a heart beat for many reasons, but that's me.

You should ask around for people who've heard both at length.

Edit - Oh, and thanks, Acrog for the linky. Always thought Wes had good ears.

I have both and like them for different reasons. Wes Phillips got it right in this excerpt from his review:


With the TosLink connection, I think the differences between the two processors became more apparent: the Grace was detailed and crisp, the HeadRoom big and warm.

I don't want to sink to the old analytical vs musical cliché, because it wasn't that clear-cut. I enjoyed and heard deep, deep into music through the Grace, but it wasn't particularly seductive. Well, gee—it is designed to be an analytical tool for recording engineers, and it shares certain characteristics with other products we audiophiles have borrowed from the pro world, including Wilson Audio Specialties' original WATT/Puppy loudspeakers.

In other words, I felt the Grace m902 was better at letting me hear differences between choices than it was at sucking me deep into performances.

For me, with toslink, the m902 is fantastic with the HD650, and even better with the GS1K.

With USB, according to Phillips, the HRD-maxed blows the m902 away.

In general, the HRD sounds slightly "veiled" in comparison to the m902, but some would say that this veil is necessary for a warmer and more musical SQ.

In my listening, I find that I crave both the analytical m902 and the warm HRD at different times, depending on mood.

feifan,
Since you own all 3 brands (Senn, Grado, and AKG) can you describe your view on the relative comfort of each for long term listening sessions? I have the K-701s and Grado SR-125s, and while I enjoy the sound of the AKGs, I find them very uncomfortable to wear for any extended length of time vs. the Grados, which I barely notice on my head. I do have a large head, which I'm sure is a factor, but I'm thinking about getting a more comfortable set... maybe a higher-end Grado. I've never tried the Sennheisers, either. Tough to determine without a local place to audition them.

My senn 650s are like a vice clamp, this relaxes with time but never fully goes away. For long sessions they dont really bother me, I just never forget there on my head like Grados.

Kevin,
Thanks for your input. Since I've decided that headphones listening is the most compatible form of music enjoyment with my lifestyle, I've come to the conclusion that even if a pair of headphones are top notch conveyors of music, it becomes a moot point if they cause discomfort and I can't forget I'm wearing them. I'm hoping to hear other opinions on the comfort of various brands... hopefully from other "big noggin" types like myself. Right now I'm leaning towards something higher up in the Grado line, as the SR125s both sound good to me and feel very unobtrusive while I'm wearing them.

Hey, EZ. I've heard others complain about the 701s, too, but they're very comfortable on my head. The GS1K is very comfortable -- and light. These two I can wear all day with almost zero discomfort. The HD650 is a different story. They're snug and would be like clamps if I didn't keep them stretched on a glass mannequin head. It all depends on your head size. I have a medium-sized head so the 701s and GS1K tend to slowly slide off or down if I move around a lot.

i have a headroom max and recently got the grace m902b

the gs1000i does sound really spacious, crisp, airy and live with the grace m902b. for serious organ and beethoven symphonies, i still prefer using my headroom max

I'm seriously thinking of a Denon AHD7000. How does it shape up with the HD650? I'm looking for a closed headphone mate for the Senns.

after the denon ah-d7000 arrived last december 2008, I have not used my sennheiser hd 650. whatever great bass or handling of beethoven and bach i loved with the 650 is a bit better on the denon ah-d7000.

there is a slight loss of neutrality on the denon ah-d7000 compared carefully with the hd 650. on music like vivaldi's 4 seasons or small violin pieces. here, i much rather use the grado gs1000i over either denon or senny hd 650.

so in short, if you love your hd 650. the denon ah-d7000 will improve on that with classical. if you love rock, the denon ah-d7000 is very exciting!

the following combo is about the best that i have ever heard led zep 4!

Thanks for the testimony. Comments as these make you say 'what the ...' and burn that hole in your pocket. I should've done so when the price was down at $650!

My voice of reason does have me wondering, 'why not the AH-D5000. It would seem that the performance differential isn't that much. The point of diminishing returns seems to feature heavily between these two models.

if you call headroom or another and beg to get the ah-d7000 for under $600, the cost/value over the ah-d5000 is large enough and justify spending the money.
if you pay full at $999 for the ah-d7000, your point is valid.

that said, i have a size 7.75 hat size and the ah-d7000 fits this melon better than the ah-d5000. they are not the same.
