And he puzzled and puzzled, till his puzzler was sore. Then the Grinch thought of something he hadn't before! A Packageful of Paradox Indeed, the iQube is quite a puzzle, and sort of a slippery customer to boot, its clever non-skid, protective outer armor notwithstanding. Ignoring...

Back this past June, when I visited Hans Oosterwaal of Qables at his new shop, audioXperience (see thread HERE), I left with him a sample of the elusive Ultrasone threaded ear-cup connector for him to have a play with. Prior to this point, although a handful of other companies including Moon...

iQube site now functional HERE i-Qube Lightweight, portable, high-efficiency Class D Headphone amplifier Electrical designed by Bruno Putzeys (Hypex UcD / Grimm Audio) and Guido Tent (TentLabs / Grimm Audio) -Runs on 4x AAA alkaline or rechargeables -PC/USB or any...

I've been poking around the diyAudio Forums recently and have been struck by all the raving about Class D amplifiers there. Does anyone here have any thoughts about, or experiences with, Class D applications in headphone amplifiers? I'm not terribly tech-savvy, but I'm left wondering why...

Following on the thread I began to discover which PCDPs (vintage or new) could be enjoyed with the DAC facility of my iBasso D1, I thought it might be useful to compile a list of known PCDPs and DAPs that function portably (i.e. on battery power) featuring optical or coaxial outputs. So feel...

I've been having such a blast with my Sony CD Walkman D-EJ2000 feeding the optical input of my new iBasso D1 that I've decided to look for another PCDP with an optical output as a back-up. Trolling the local 2nd-hand shops I've seen a Sony D-15 (20 Euro), Sony D-EJ100 (13 Euro), and a Sony...

This past Saturday, I had the pleasure of spending a most delightful afternoon with Hans Oosterwaal at audioXperience, his brand spanking-new high-end audio and head-fi specialty shop. Of course, many of you might already be familiar with Hans from Qables, his online emporium specializing in...

Hello! I carry around a Sony CD Walkman D-EJ2000, which has an optical output. I also use a MacBook which has both optical and USB. So I'm looking for a DAC that has at least optical input and possibly also USB (if the sound is somehow superior for the Mac). So what are my options at...

Has anyone here gone or planning to attend the High End Show this weekend? Would love to have news of any headphone-related introductions with photos, if possible. From the brand list I see Beyerdynamic, Denon, Goldring, Grado, Heed Audio, JVC, Lehmann Audio, MB QUART, Panasonic, Philips...

Anyone looking for a solid, better than entry-level portable amp might be interested to know that Norm has lowered the price on his remaining stock of Go-Vibe V5s: Go-Vibe V5 ($45) / V5S ($48) Can the V7 be far behind?

Hello, Having gotten a taste of Apple with my MacBook, I'm looking to rid myself of Windows entirely by replacing my desktop PC. There are two interesting options so far: 1) iMac G4, model PowerMac 4.2, 800MHz 15-inch display L2-cache 256MB 768 MB RAM hard disk 60GB superdrive...

Well, I missed out on the fun, but I'd sure like to hear all about it! Already spotted some nice photos on the German forum here: http://www.hifi-forum.de/viewthread-110-4682.html So any Headfiers who made it, don't hold out on us!

No kiddin'. No foolin'. No hi-jinks. No shenanigans. Let's all check those egos at the door, and personalities as well. So let's roll up our sleeves and get down 'n' dirty with the open-back flagship of the Ultrasone line-up! I'll kick off the festivities with a frequency response...

About bloody time! SendStation Dock Extender Just hope it's not obscenely expensive.

I finally go 'round to rolling another set of op-amps in my Go-Vibe V5S. Is there a burn-in period for op-amps one should get through before evaluating them against the stock set?

Click HERE. Read. Discuss.

So now that I've gotten a taste of what the Go-Vibe is capable of with a 24V external power supply, I'd like to take that same magic on the road, as it were. I've noticed that most common rechargeable 9V batteries actually measure 8.4V. So I was wondering if making a battery pack of 3 such...

Someone posted a link to the new issue of online magazine Affordable Audio in the Amplification section, but it's just as relevant here: http://www.affordableaudio.org/aa2007-01.pdf The zine downloads as a PDF file. Scroll down to page 4 for the Ultrasone review. A nice write-up and some...

Sticky Alert! Having just ordered the new rollable Go-Vibe V5S, while currently knowing absolutely nothing thus far about op-amps, I thought I'd best tap into The Knowledge here by beginning a thread with Sticky-potential where the more experienced members can share their theories and...

Hello! Now that I've pulled the trigger and ordered a Heed Audio CanAmp for my main hi-fi rig, my thoughts are turning toward a suitable smaller-form amp companion for desktop and portable use. Headphones used will include Ultrasone PROline 2500, KSC-75, PX-100, and Ultrasone HFI-650...

Much as it pains me, I cannot afford the Ultrasone Edition 9s even at the ridiculous discount offered, so I thought I'd pass this along for the benefit of my Head-Fi brethren in hopes that the karma train will one day pass my way. Click Here Cheers, Dex

(Original thread title: "Ultrasone PROline 750, 2500, or HFI 2200 ULE?" Dear Reader, This thread has evolved substantially since I started it as a simple newbie request for information about what was then a little-known and oft-misunderstood brand of headphone, at least within the...

Greetings, All! (I realize that this is a rather LONG post, but if you bear with me, some might find it rewarding!) I’m relatively new to this fantastic forum. My initial interest had been in run-of-the-mill home audio, and for the past few years I’ve been posting regularly on the Pink...

Hello! New to the forum here and also a new MacBook / iPod 5G owner. I've been reading posts here about line-out docks with great interest and I've taken the plunge on a relatively new RF remote / line-out dock combo called CruiseControl from Gear4, based in the UK: I purchased it...
