    Sennheiser HD 700 Impressions Thread

    I'd like to acquire some DIY chops and am thinking about devising a "practice" project, something like changing the caps in an old piece of gear. If I screw it up, it won't matter.   Would anyone be able to recommend a good website or a YouTube tutorial on this kinda stuff? I found what...

    Sennheiser HD 700 Impressions Thread

    I couldn't resist trying it out sooner rather than later:   PC running Foobar with ASIO output ---> Asus Xonar ST PCI card DAC ---> Little Dot mkIII pre-amp ---> Rhinelander amp ---> HD-700's   1) Low noise floor 2) Power to spare 3) Well-defined bass 4) Crisp and clear high-end...

    @Mark, regarding the AD8397 op amp, I'd be interested in trying that in my Xonar ST, but it's a SOIC-8 - is that correct? The Xonar uses DIP-8 op amps. I know there are adapters and such, but I don't even own a soldering iron, yet... Actually, at a not-too-distant future time I'd like to change...

    @Mark: clearly I mis-read some posts on other forums about the LD and Rhinelander, which led me to believe they're DC coupled. Damn internets.   Thanks for putting me right, your post tells me exactly what I wanted to know. In a couple days I'll get down to juggling amps. Right now I'm only...

    @Mark: thanks for your post and sharing your knowledge regarding pairing DC coupled amps.   Sounds like an intriguing possibility, and I'd like to run the following case scenario by you:   Were I to use the Little Dot mkIII tube amp as a pre-amp, sending the output to the solid-state...

    Sennheiser HD 700 Impressions Thread

    Just thought I'd offer some words to anyone reading this who uses an Asus Xonar ST/STX sound card, either as a headphone amp for HD-700's or running the Xonar's line-out to a dedicated headphone amp .   Yesterday I changed the stock op amps as follows:   1) I/V = 2 X LT1364 2) Buffer =...

    @Mickey: thanks very much for your excellent post and sharing your experience/insights. Sounds like the Lyr is a good bet, but unfortunately it's beyond my price range right now.    @Mark: I'm eager to hear your impressions on how the Asgaard pairs with the HD-700's.    Anyway, I just...

    Sennheiser HD 700 Impressions Thread

    I've had my HD-700's for about a month and have generally been enjoying them very much. My only beef is with the mid-range spike, but I believe that can be tamed with the proper amp.   Right now I have the Lehmann Rhinelander, which is a brilliant amp. I used it with HD-650's, DT-880's and...

    HD-700 distortion?

    Thanks for the quick and helpful replies.    Problem solved, and I feel foolish: in foobar there was a hidden setting I configured incorrectly some time ago which boosted the output and caused clipping. At least something good has come out of this: I now have a better understanding of the...

    HD-700 distortion?

    Hello everyone, I'm new here and am hoping someone can help/advise me.   I just bought a set of HD-700's not quite one year old and with only twenty hours break-in. I've put in a dozen hours over the past week. I use a Rhinelander amp.    So here's my issue: Listening to a high-res flac...
