General comments about mark2410's review style:   Pros: Good product selection (ie., when compared to plethora of new junk released, mark2410 grabs the real goodies) Good photography   Cons: No bulleted intro/summary -- important info like price, main features, dimensions, and manuf. web links should be FIRST -- in bullets -- and later expanded in that order later (see 1, 2 below) Too long (see 1, 2 below) Not written/stylized for the web...
Oh ... okay, I finally got iRiver's branding strategy.... Barbie Astell and Ken Kern .... toys!!    Looks like Barbie doll never got hitched ... even after all these years ... marriage is so overrated, anyway.
I haven't seen a schematic for the Bottlehead Crack .And while that is a different style of tube amp than MSSH, I did note that Bottlehead offers a CCS upgrade called "Speedball" for the 12AU7 section: http://www.bottlehead.com/store.php/products/speedball-upgrade-for-crack-amplifier   Will it work with the 12AU7 SSMH variant?   EDIT: Here's the C4S Camille Cascode Constant Current Source kit: http://www.bottlehead.com/et/adobespc/C4S/c4s_kit.htm ... it's an LED-based CCS...
I went to the iriver wiki page as well as the official iriver web site and can't find any info on who "Astell" and "Kern" are? Are they project engineers? Or is it a "brand name" ... like Lords and Taylor? Anyone know? Thx!!
How hard is this device to get into? For Apple and similar "idevices", there is $10 kit you can get to easily pry open w/o any damage to unit. It's important to be able to get into one of these units according to Bear Grylls and Survivor man and all those "reality" shows". Reason: you may need the battery inside to, say, start a fire if there is some sort of "emergency" ;)
Cool, but in order to conduct any useful "engineering analysis" we need properly-lit and focused macro photography, preferably in multiple sections, and (as I noted before) on BOTH sides of the board. Also, that daughter board needs to be lifted to reveal the covered section of main board underneath.   Come on folks ... take that cover off, focus your iPhones, and snap ;)   HINT: Here's example of GOOD internal photography: Image link (full...
Ditto this comment! If any AK120/100 owner is brave enough to peek under the hood, snap a few pix with their iPhone, and post 'em in this thread ... well, thx in advance for the legwork ;) Oh ... BTW ... don't forget to photograph BOTH sides of the circuit board.  Thx again!
Good job on the photography!   Now, can you re-open your unit and show (photograph and post) what's on the OTHER side of the PCB. We'll probably see the twin Wolfson DACs and maybe other interesting stuff.    Just looking at these images reveal nothing really overly special about the device ... i.e., why it may sound as good as some claim. That said, shorter trace distances (better layout) and better-written software as well as a high-performance decoder (the main DSP) --...
Haven't heard the Rocoo BAs yet. What are "Studios"? Link, please!   The AK's biggest downfall is, of course, $$. Some may defend the $$ given its size-to-perf ratio. But come on ... can a few centimeters off the dimensions be worth THAT much? Maybe this brand/model is for elites ala Tiffany ... Chanel ...Sharper Image, etc and I'm none the wiser ;) Certainly that name Astell-Kern sounds "elite", as is its royal packaging and artwork. Reminds me of the Colorfly CK4 vs....
