JDS Labs C5/C5D (pg96) portable amp/amp+DAC - Page 105

post #1561 of 3364

Received my C5D in the mail today. I tested it with my Mad Dog headphones and my RE-400 earphones. Everything is great with the Mad Dogs -- no hum present. It is noticeable with the RE-400's, though -- enough so that it could make listening to music with soft passages problematic for those with more sensitive IEMs (or for those who are particularly picky). Granted, the RE-400's are sensitive enough that there is a noticeable jump between having the volume all the way down (or silent, in other words) and having it one step up from that, so I'm not sure how representative my experience is.

 

That said, the hum doesn't appear to change with volume, so I think tvolpe1600's observations may be something else. Also, what I'm hearing only lasts for about a second or two once audio output from the computer has stopped, which goes along with jseaber's note that it stops when the DAC is paused. Finally, what I'm hearing is not present when using it as an amp.

 

So, then...I guess the question is: am I going to be sending mine back? I'm still undecided, but am honestly leaning toward "no" right now. The reason is that I bought these for my Mad Dog, which needs amplification to get as loud as I like and sound its best. I typically don't listen to headphones with an amp unless the pair I'm using really needs the extra power.

 

In any case, major kudos to the folks at JDS Labs for how they've handled this. Your open communication and commitment to excellence puts many of your competitors to shame! :beerchug:

drm870: Check your email, or see this morning's announcement. We're sending advance replacement C5Ds to everyone who ordered last week.
 
Production is now perfect.

Okay, got the email. Seems like less of a hassle the way you guys are doing it (versus how other exchanges by other companies have been handled) than I had expected. Will email back. :smile:

This is slightly random, but what kind of finish does the black C5D have? I received the updated ODAC case today and it looks great! The case feels like a smooth/bumpy metal though; no chalkboard-like texture from the C5 nor a unidirectional grooved surface like the original ODAC case. It also seems to attract fingerprints more, but I don't mind too much.

"We met a few Android users at the 2013 CanJam who successfully used C5D natively (i.e., with any app). Some Android phones and tablets output UAC1 natively."

Do you have a list of Android phones capable of using the C5D with any apps? Or specifically if the Samsung Galaxy S4 will work?

We're letting users compile the following list of natively compatible Androids, and will contribute as we gather information:

That's the labor of OCD engineers and metal finishers here in the USA. Each case is bead blasted to our requirements in a custom, computer controlled rig. Then it's subjected to an extreme chemical process before anodizing. Full secrets here.

Cool! I really like the finish the C5D has vs. the original C5. (I had a C5 some time ago that I ultimately sold...a decision I regretted until the C5D was announced.)

 

Anyway, I feel like I should say that the remarks I posted regarding my C5D unit was not meant to be a negative review. Rather, it was my attempt to justify JDS Labs' decision to fix the issue for those who might be wondering if it was needed or necessary. That's why I posted my impressions despite the fact that the problem has been fixed.

 

Just thought I should clarify, that's all.

Does anybody knows how the C5 compares to the Headstage Arrow 4N?

Can anyone comment on the C5 with the Westone 3? I was thinking with the recessed mids of the W3 the slightly forward mics of the C5 could be a great combo...

We have rubber bands in stock. Mention your request during checkout and we'll send a few for free. These will soon be part of standard packaging (not quite there yet).

JDS Labs rubber bands? Sweet! I don't like to use those on my rig in order to keep it as clean-looking as possible, but I'll wear one instead. tongue.gif

I am catching up just today hearing about the C5D and have a few questions that I didn't see answered in the thread.  I hope some of you can assist me with these.

 

To use as an amp/DAC with my Iphone, I noticed on the JDS Labs web site that CCK is required along with iOS7 which is already installed on my Iphone 4.  This is probably a silly question, but what is CCK?  

 

The price says starting at $249.  What are the options that increase the price and is there a premium for Apple compatibility?

 

What is the difference between the C5D and V-Moda Versa?  It is truly a lower cost alternative to Verza with similar features?  

 

What is the power of the C5D in mw/channel?

 

Is it powerful enough for respectable performance from Mad Dogs/Alpha Dogs?
