source lately is 24bit vinyl rips and other various hi-rez files...

In this corner....a MacBook Pro weighing in with a built in mini optical jack capable of 24bit-192khz stereo output (although the Audio/MIDI utility only has a setting for 96khz?) And in this corner...the feisty little M-Audio Transit...with its fancy installer, preference pane and USB...

Just got my 131 in the post today....only took 2 days to Melbourne....same as when I got the 151. Wow. Straight out of the box...this sounds amazing...the detail difference is noticeable....can't wait to roll the caps in about a month when I get used to it.... I was skeptical about going...

Thank you....just the advice I was needing to hear.....and since the post I've dug more and had things come up to support just that....Cheers

So...I've just upgraded my DAC to the Keces 131 (should be here in a coupla days) from the USB Keces 151 and am busy thinking about the best way to go about connecting the new gear. Thee source is a MacBook Pro which has a 24/192 optical out in the form of a mini-optical jack. I had thought...

To the Maniac.... Currently running the 151 from my macbook pro....but considering upgrading to the 131 via the optical out as I've recently got into 24/96 vinyl rips.... Is the optical out on the macbook pro...quality enough to justify the upgrade or is the advantage of the 24/96...

Good bass out an iPod (using headphones) the way the iRiver's can is there? Is there some secret method? Perhaps editing every single (4000+) mp3 files seperately using Peak and increasing thee bass that way? Kidding of course. I was so set on getting the 20GB H10, till I found out it is XP...

i dont understand how they continue to manufacture sell a product with such an obvious flaw as the eq. (seriously, people dont notice that when you put on bass boost it distorts?!?!) i guess it is because people are buying them...but yes..why people here love it surprise to me as...

My current outside sealed portable phone (for exclusive portable on the go in the city) is the px200....suits my needs and tastes perfectly. I am curious if there is an option with that same full deep bassy slightly rolled of highs sound but...not in a traditional headphone (top of the head...

someone get one and tell us about it. i would, but i just got a 450 and am content.

Specificaly with the (ooh i forget the name) little plug in line out adapter for the 3 and 4G's...? OR does bass boost actually work that way.....without distortion? thanks aye....

Well, I must correct myself as I proceeded to do some further imp-350 and 450 tests. I ran a selected mp3 track in both players side by side with the EQ set flat on both, volume set to 30. The headphones I tested were both a well broken in Sennheiser px200 as well as Sennheiser HD 25-1, also...

Well, I've finally answered the nagging questions and the results are interesting!! I went and purchased an imp-450 and got the chance to get to the bottom of the imp 450 and 550 EQ differences in relation to my trusty imp-350. First off, no disrespect to the imp-350; it’s no slouch; it's...

As the originator of this thread...i thought it time for an update. They have been locked away in my sound-proof studio for the last...err.....6 days...with a 5 song cd on repeat....24hours a day at a pretty decent loud volume with the bass turned up high...some good heavy/deep bass...
