    Where are the 16gb flash players???

    I'm looking for a 16gb flash player. -Iaudio 7 16gb is out, but is too much $$$ at $299. -Zen 16gb is $249 and Sansa View 16gb is $199. The last two were anounced a while ago and were supposed to be out in October...well...it's October! Anyone know when they will actually hit the street?

    Shure SE420 First Impressions

    I picked up my SE420 package at lunchtime (FAST shipping by Headroom!!!). My first impression is VERY positive. This surprised me after my disappointing experience with the E500. Typically I listen to Ety ER4P which I consider to be very fast, detailed, and upfront vocals. I also like my bass...

    Ipod Hiss Gone with Rockbox...Why???

    I have an Ipod 5.5G with Rockbox installed. With the OEM software, I get a hiss with IEMs. With Rockbox, the hiss is gone. Anybody know what about Rockbox does this? Whatever it is, why wouldn't Apple do the same? I must be missing something, because I would be extremely surprised if a...

    Anyone have DT770 and DTX50?

    Can anyone compare these two? I'm still looking for DT770s in an IEM. And any idea when the DTX50 will be released in USA (it was supposed to be Sept 06, then March 07, then...)?

    Alternate Takes!

    I HATE ALTERNATE TAKES ON REISSUES. What is the point of subpar, often poorly mastered, bastardizations of final takes? I have NEVER heard an alternate take as good as the final take. Venting, that's all I have to say.

    Go-Vibe V5S: Why 8397/825, not 8397/6171?

    I have a Go-Vibe V5S with LM6172/6171, and I have an AD8397 on a browndog so I gave it a shot. With the 8397/6171, everything seems to work well - DC offset was ~0.5 mV and it sounded great. Why is 8397/825 a stock option and not 8397/6171? Am I at risk using the 8397/6171 combo? Hopefully...

    Rockbox for 5.5G 30Gb Ipods Now Available!

    I just wanted to let everyone here know that Rockbox now works for 5.5 30Gb Ipods. For me it is fully functional and I'm loving it. A huge bonus with respect to the 5.5G Ipod is that running RB pretty much gets rid of the annoying hiss with IEMs.

    Mizzurah?

    Warning: Silly rant to follow! Not that it is in any way important, but one thing that bugged me on a superficial level the other night was the newscasters and analysts using "Mizzurah" for "Missouri". The newscasters don't actually have any sort of an accent in normal speech. Only when it...

    Amp Gain and PS Question

    This might be kind of a rambling and vaguq post, but hopefully I (and some readers) will learn something in the process. I listen to DT770/80 while stationary and UE SF5Pros while on the go. I have built 3 Cmoys (9V) and a Pimeta (9V portable). For each, to avoid hissing with my SuperFi 5Pros...

    South Florida Travel Advice

    Hey Everyone, I posted this question on TripAdvisor's forums and basically got no responses. Since the people here are so nice, I figured I would ask here! My wife and I are flying to Miami April 8-13 (Sat-Thurs before Easter). We are 30 year-olds from UpperSoCal, who have never been to...

    Points of view: HeadFi vs HydrogenAudio

    Getting into HeadFi over the last year or so, and reading over at HydrogenAudio periodically, I have become confused about the somewhat opposing points of view. Aside: If this has been beaten to death before, let me know. Let's start with the premise that we all want our music to sound...

    BUF634P Silk Screen Differences???

    Hi, I bought three Buf634P for my Pimeta on EBay. When I tried them out, I found that one was dead. Hmmm, strange...so I bought a replacement from a HeadFi member. Tonight I noticed that the Ebay ones have a different silk screening than the one from the HeadFi member (who is well-known and...

    Do people with bigger heads experience more bass?

    Whenever I press my full-size headphones in towards my head, I experience a much more bassy sound. For a given headphone, there should be more pressure exerted on those with a bigger head. Thus the big-head sound should be similar to pressing the headphones in for those of us with smaller heads...

    Pimeta Ground Buf634 Question

    I just finished putting together my first Pimeta (9V portable, class A, 220 ohm bandwidth resistors, added 75 ohm R8s for my low-Z headphones). Initial measurements revealed that something was definitely wrong. To make a long story short, one of the three Buf634s that I got on Ebay was blown...

    Strange Recheargeable 9V Problem

    Hi, I bought a cheapo "Titanium PowPower" 9.6V, 160mAh battery for portable amp use. I also bought the 2x9V smart fast charger, which seems to work great (tested on my other 8.4V rechargeables). However, there are some wierd issues with the batteries, I'll describe the symptoms and possibly...

    Super.Fi 5 Pro = First Eargasms!

    I found a great deal on some barely used clear Super.Fi 5 Pros and received them yesterday. For reference, I own or have owned: E2c, V6, HD201, DT250-80, HD25-1, and KSC-75. I have not heard any other high-end headphones, so I can only compare with what I have owned. My source is a 4G Ipod...

    Single version of OPA2107? Or similar?

    I searched but could not find an answer. Does a single version of the OPA2107 exist? I've discovered that this is my favorite opamp in Cmoys, but if there is no single equivalent, then I cannot use it in a Pimeta. Any other similar sounding opamps that aren't too current/voltage hungry for a...

    2 Batteries last longer than 1?

    This might be a silly question, but here goes. When building an amp, say a Pimeta, what is the purpose of using two 9V batteries? I have been under the impression that more batteries equals longer life, but just thinking about it now, I'm not so sure. In series, you get 18V. Fine. But the...

    Cmoy: 9V versus 18V

    Hello, I am putting together a Cmoy and need to decide on a battery configuration. I am planning on using rechargeable 9V or 9.6V. Opamps will be the usual suspects: 2227, 8620, 2132, and perhaps 8397 if I can work out all of the stabilization schemes from Tangent's website. I am planning...

    AD8397 in Go-Vibe?

    I searched and didn't find an answer to my question. Has anyone tried the AD8397 in a Go-Vibe? If so, did it work out OK? I know there are some offset issues, but I don't know if the GoVibe circuit has the corrective elements. I have a sample AD8397, so if I put it in, I need to measure the...

    My impressions of the Go-Vibe V3b

    Hi everyone, Last week I ordered the new Go-Vibe V3b (at least that's what the pcb says) for $69. This is the one in the aluminum Hammond case, with no engraving. I chose the stock AD8066, red LED, and a gain of 4 for versatility. Currently my stable consists of Beyerdynamic DT250-80, Shure...
