Many of the guys on the C&C BH thread have had great results with the C3 into a BH.  A few have compared it with Ipods > LOD's > Amp and preferred the C3 by a fair margin.  I have one on order  and currently  I have the BH amp with a 5.5 Gen iPod Rockboxed.  I really like it but find that updating, everytime I want to shuffle my playlist a pain, and I don't dig the software too much.  Thanks for the info on your results.  I appreciate it.

 

By the way I would suggest trying another LOD.  I felt as though my Fiio LOD was good but the one I made had a bigger soundstage.  In my experience the Fiio gave the impression of more punch and perhaps cleaner but it had less musical information than the LOD I made.  My son has the Fiio now along with my old E5.

has anyone directly compared the c5 with the c421?

 

im loving my c421, its such a excellent amp. i am awaiting to get my ipod  lod back from ted. to test the c421 straight up.

 

 

does the c5 follow the same principals as the c421 ie: completely black staging, i get no volume noise,no hiss,just pitch black.

 

also is it transparent. the c421 is extremely transparent it adds no color whatsoever to the music or sound.

 

i am considering the c5, but my c421 8620 is so great i just wonder if the differences are subtle or major? in sound other than other physical asthetics

randomkid have both the C5 and the C421 8620 (if it is not sold by now). Anyway he thinks the C5 is better.
Read his posts and if you are missing something you may ask him about details?

C5 is better, I have sold the C421 but did do a comparison before it went.
Just waiting till I'm next in the computer to post review including comparison to C421 AD8620 and O2

well thats good to know it improves on such a already great amplifier (c421)

 

when i got my jds labs c421 i wasnt expecting what it is in terms of sound quality and build. for the price and sound. these amplifiers both c421and c5 contend with amps double their price imo.

 

eager to hear pros and cons between both c421 and c5

Hi all!

I've glanced through all 49 pages in this thread so far, but couldn't find any proper info about the synergy between the C5 and Beyer DT880/250 Ohm.

I've been trying to decide between the C5 and C&C XO2 (more expensive and LOT more power) to pair with the DT880/250. Although the XO2 is supposed to be very powerful, I'm not sure about its quality of sound. From everything I've read here, the C5 produces high quality sound, but I don't know how well it can deliver that quality to the DT880/250.

If someone has tested this combo, can you please share your opinion?

Thanks in advance!

Thank you I think I will try the c3 again with another interlink.

C5+EX-1000+DD socket 1+jazz music= eargasim. I think the reason why treble because hot at times is not the fault of the amp but it is the fault of the track, it is just recorded that way.

According to John and the power calculations, the c5 should provide its quality to that phone with no problem.  As for a specific "synergy", I can't say as I haven't heard them.  But you shouldn't be missing any of the c5's quality with them if you want them to be as neutral as their sound signature allows. :-)

Thanks a lot for the response. smily_headphones1.gif

If I remember correctly, John's calculations assumed a sensitivity of >100 dB. The DT880/250 is less efficient at 96 dB. And from what I understood, the sensitivity plays a major role in the amp's ability to perform with a particular pair of headphones. From what I've read in this thread, the HD800, although having a higher impedance of 300 ohms, has a higher sensitivity of >100 dB.

So, this sensitivity issue is what has me worried about the capability of this amp to perform well with the DT880/250. It would be great if someone who has experience with the combo can chime in.

anyone compared C5 to Tralucent T1? would be curious to hear impressions from those who had a chance to compare.

 

what i find hard to believe is C5 bests O2

It depends on the context of "bests". For a portable amp, I think the C5 trumps the O2 for overall sound, usability, and storage. For a desktop amp, I find the O2 to be a bit more transparent. For synergy.....that's another story.

The O2 is still better, but not by far. The C5 has a more intimate presentation, the O2 is more airy and spacious.

Yaaaay, so I'm not crazy after all! That's really re-assuring, so thank you for your observations. :)

I posted the soundstage difference in the O2 thread and people were surprised about my finding....even after multiple by-ear volume matching trials they were surprised. >_<

 

And yes I totally agree that the O2 is just a bit better than the C5, but mostly due to the spacious presentation.

I just noticed a strange thing going on with my C5 today.  This morning when I powered on my Cowon Z2 + C5 setup and hit play, I got silence for about 5-7 seconds, then static and noise started coming in at a gradually increasing volume until it hit the preset volume I left it at before powering down the night before (and left it charging overnight).  I thought it was strange but didn't really give it any thought and chalked it up to a one time fluke.  But when I turned it on again later in the morning, I got the same strange sound.  So I did some testing throughout the day and it seems it's got to do with the bassboost.  If I leave the C5 turned off long enough (not sure exactly how long yet) and turn it on when the bassboost enabled, I will get this strange sound.  If I turned on the C5 with bassboost disabled, then it'll play music and the correct volume right away with no noise or distortion.  It makes sense that it's related to bassboost since I only started using bassboost yesterday.  I was able to record couple clips of the strange noise happening in 2 different instances using my phone and I'm attaching it here (rename to wav for playback).  Did any of you out there experience something similar?
 
 
I do have to also point out that one of the traces on the PCB had it's soldermask scratched off due to being right under the rail that holds the PCB in place.  The fit is real tight and I had to wiggle the PCB to get it out and I suspect that it got scratched off then.  I emailed John and he said that as long as the anodizing is not scraped off it should work fine.  And if the C5 does short due to metal-to-metal contact, it should just short out one channel and he will replace the enclosure.  I'm attaching a pic of the scratched off area.  Don't know if this has anything to do with the noise issue above though.  Just a heads-up for those of you that are doing mod/dev work.
