did you try plugging your canamp to another wall socket?

Ah, the love on the Canamp is still strong in most of us I'm still very much enjoying my ultra-modded Canamp By the way did anyone try pairing the Canamp with IEMs? I tried plugging my Shure e4c to it and it sounded NO difference with plugging it straight to my stock iPod 5.5g!

i'll still recommend the e4c. You bought a fake pair, and you definitely need to listen to a genuine pair this time!

I have a pair of e4c and I plan to stick to foamies. I wonder can I use Ety's foamies on my e4c? Ety's foamies are cheaper than Shure's though TIA

oh my... do they look like these? try searching "fake e4c" in this forum's search form, you'll end up with a handful of links and info. I have a pair of e4c myself, and it is grey top bottom white.

the stock Heed does sounds amazing when I upgraded from a LD2+. But unfortunately it reveals its flaws when you compare it with other similarly priced headamps (e.g. PPAv2). If possible do try a modded Heed, you'll be very much amazed. Still, i'm very much in love with my Heed (of course, a...

The owner of the Heed chips in. My Heed Canamp is not in stock form. It has upgraded power supply caps, dual regulators, upgraded input decoupling caps, and has a pair of OPA637s on a browndog. I have tried a handful of opamps on my Canamp (AD823, DY2000, OPA2107 etc) and imho the 637s has...

from my experience, my stock Heed loses to a PPAv2. oh well, the PPAv2 is like USD200 cheaper than the Heed. but please don't get me wrong; i'm still sticking with my Heed (and this would be my last commercial amp!)

I have the exactly same setup before: EMU0404 PCI -> Heed -> K701. Overall i would say it is just so-so. The stock 0404 has rather narrow soundstage and bright treble. Seriously, the ZL is much better imho.

so far i found 3 opamps that suits my K701 darn well: OPA637s on browndog, AD DY2000, and National Semiconductor LME49720. The DY2000 performs the best for vocals; LME49720 has loads of details, strong bass, but it lacks the musicality in vocals. The 637s have expansive soundstage, but i seem...

I tried the NE5532 again 2 days ago, when i was playing with my opamp stash. Urgh, it just sounded horrible to my ears. One thing is for sure: the NE5532 kills loads of details

yes, Zhaolu means morning dew in Chinese.

=) here's a brief review on my ultra-modded Heed CanAmp. One obvious improvement is the noise floor has been kept to almost zero even at max volume. However this does not apply to all opamps i have. The LM4562 and LME49720 has noise problem at max volume, and dual 637s on browndog has noise...

i took my CanAmp out for a walk this evening. A car stopped in front of me and dragged my CanAmp into the car. I was horrified and shocked, stoned for 10 minutes at the crime scene. Upon gaining conscious i dashed back to my apartment for help... and there lies my CanAmp in front of my door...

:P d-cee, it should be the "AD"1852

:P i'll get nightmares if i continue staring at that picture for another 5 minutes!

i did not expect this thread will have so much twist and turns, especially Hi-Finthen who used to be a die-hard CanAmp fanboy. To me, Dan is one of the best sellers i ever met. He aided me a lot with my CanAmp purchase even though he does not get my order. All these negative comments are...

geez boys and girls, can you please stop it? I for one do not wish the mods to close this thread

haha i'm not sure too. Some friends of mine commented that the CanAmp's RCA tracks are too near to the transformer, and cited from my friend: "The Heed very much uses an extremely simple PSU (tranny, diode, filter, secondary filter) which which can be far improved upon with simple regulation and...
