hi everyone, i need to contact fiddler/eugene, the former man behind fidaudio. he closed his website and didn't respond to mails/pm i sent him over the last weeks. is there anyone out there who has a working adress (postal/email) or who could contact him in my name? please pm me. thanks in...

i bought one of these, too. really surprisingly well made. i agree with lini, that this one seems to be made by ANSMANN. again: adjustment of the proper voltage needs a voltage-meter/dmm. the adjutment wheel on the backside covers a sort of rotary switch that gives me 5 steps from 13,5-25,8v...

1. yes, it's possible to use a single->dual opamp adapter (browndog eg). be careful to choose the right one (there are versions for soic and dip - most likely you'll need dip). tangent sells some adapters. note: opa 637 needs at least gain 6, better gain 8 to work flawless. opa 627 (being unity...

you'd find all the infos on the go-vibe hp: http://members.shaw.ca/storage_2/hea...eplacement.htm /edit: i'd recommend to give your new amp some time to burn in, before you change the opamp. at least those electrolytic caps inside need some time (50-150h), to let the ics shine in their best...

the dt880 sound nice and refined right out of the box... 'though they'll get even a little better over time. at least that's my experience...

while fiddling around with the rail capacitance of my ppa 1.0b i also began bypassing c4 and c5 with small ceramics and fkps. the sound was quite nice until i decided to try this also with c2. after some strange experiences with my ongoing moddings of the wna rails i developed some sort of...

truly the best decision to buy some music instead of yet another peace of promising gear... congratulations, appar!

as far as i know, glassman has still some of his diamond buffers on stock. they should be cheaper than the intersil-buffers, too. on the other hand, from what i've heard, building the ppa v2 could save you a few bucks in comparison to the ppa v1 + gm 2nd gen buffers. there are only a few...

not necessary, steviedvd. in fact the wna is the only amp i'm aware of, that literally needs that feature.

what is going on there, appar? every day a couple of new threads, where you consider different new amps or cans. give it another 14 days and you will end spending your money for holidays to relax from thinking things over and over again (instead of cans or amps).... seriously... as far as i...

with the dt880 and hd650 i'm using gain 6 in all my amps. using the emu 0404 at 0dB as source, it allows me to listen to most of my music at 9-10 o'clock. some classical pieces need 12-1 pm. to rock around sometimes 2... but never more. so... that gain setting is pretty universal and leaves some...

calculate the power dissipation: P = (Vin-Vout)*I = (24-9) * 0,1 = 1,5W thermal resistance is then: Rth = (Tmax - Tambient)/P = (125° - 50°)/1,5W = 50 K/W most likely that's too much for that little ic (check the datasheet), and things will get worse with increasing output voltage of your...

let's use the comparative term "darker" instead, as suggested above - they'll stay darker than the dt880 for example... even after 400 hours... no need to argue against that. if your source and/or amp has a darker presentation itself (like my h/k amp for example), any differences will be...

hey, duncan... glad to hear, you're still maturing...

if it is the folding-mechanism, you're after, you could also take a look (and listen!) at beyerdynamics dt660 (closed), dt440 and dt860 (both open). they use the same encasing as the ultrasone with the usual drawback of reduced wearing comfort (uhh... those pads are just a bit too thin and the...

chris, i can see you fitted input- and output-caps while using ad8610. in case your source is dc-offset-free, i'd recommend to get rid of both input- and output caps... you'll be surprised about the hidden qualities of your amp, once the veil is lifted... /edit: if you plan to use the...

don't try to domesticate that hedgehog, mike. his "fear" warrants survival once he's faced with real predators... there are enough cruel humans out there. watch animals from distance, enjoy them and allow them to keep (and train!) their protection instincts.
