JDS Labs C5/C5D (pg96) portable amp/amp+DAC - Page 40

post #586 of 3339

I had a question about battery, if I have the C5 connected to my laptop while I am using it how is the device getting powered? 

My concern is having it connected while I am using it will decrease the battery life as I am thinking it is continuously charging and discharging which is a bad thing.

Mr. Seaber answered this in a previous post, but I think the USB connection powers the C5 and any remaining current available through the USB connection will charge the C5's battery.

When I charged the C5 a few days ago, while using it, the LED went from blue (light blue indicating charging while using it) to green. So I'm guessing when the battery is fully charged and you're using it, you're bypassing the battery?

O yea missed that post, thanks for the clarification, good to know it doesnt effect the battery life.

Arrow 4G vs C5 

 

Just an update on C5 vs arrow 4G as I think few members on the forum are deciding between the two. While arrow 4G wins the battery, slim factor and extra features which for most IEM/gears dont make a hug difference I find that I C5 is more neutral which is a good think in my view. 

I want to say C5 is a better sounding amp than arrow 4G however as it is they are on equal. To be fair arrow 4G wins due to the slimmer nature and its provided extra feature which can be useful for the right gear but having said that you are required to pay extra for those features and sadly the customer support of arrow 4G does not have a good track record. Arrow 4G is as slim as it can get and there are very few amps which are that slim.

 

I think C5 with the current asking price is a great sounding product. I enjoy its slightly forward neutral presentation more than my O2. It feels more energetic compared to O2. 


I think the key point is synergy. While I love how CK100PRO pairs with C5 the pairing with arrow 4G is no where as enjoyable for me as the it is with the C5. I dont think there will ever be a one amp to rule them all. 

 

Comment on C5 heat:

When C5 is getting used and charging it is ever so slightly warm on hand. I would say the case feels like 25-35 degree celsius however I might be wrong as I think it is cooler.

 

Once the charging is done and the light has turned green and it is getting used the case is almost as cool as it is when it is off which is of course a great thing as heat normally means wasted energy. 

 

Comment on bass:

I never considered myself a bass head however I do enjoy a nice punchy bass slum. I really enjoy the bass and bass boost with the CK100PRO however I find the bass boost to be too much for my other IEM. I need to listen to them in more detail however issues like bass and treble are very subjective as each ear likes a different tunning.

Loving my C5, really loving it. ODAC and C5 stack nicely, I am yet to test the matching of ODAC+C5 in more detail but I was just blown away with how it matched with CK100PRO.

Just a little...

But the C421 may be sold, i'll miss it but it has been great. The C5 is just that little bit better.

I hoped for a good amp when I decided to go for the JDS Labs C5. From what I read here and there about this little amp I thought that it might be what I was looking for. The idea was to match it with a Beyerdynamic T5p, and that is still the case, but it is indisposed at the moment.

The amp arrived yesterday and I could not wait for trying this little amp out.. only problem was that I did not have any suitable cans for it.
I thougth it might not be a good ide to try the Sennheiser HD800 and ruin the first impression of this well spoke of amp, but I could not wait...

What can I say? Where should I start? First of all I am impressed of this little amps performance, and how much fun they bring into the music listening experience. Wow! The HD800's have deep bass, and with the Moon Audio Black Dragon V2 cable they get more and firmer bass. I love how the HD800's sound with this cable (I do not like them with the stock cable) but I have always considered them a little bit bass shy (not that much of a punch - if you know what I mean?), even on pretty expensive dedicated desktop headphone amps. I turned on the "Bass boost" switch on the C5.. and I have to admit that I have not turned it off again.

Bass is one thing.. but there is more.. hights.. depth.. width.. details.. instruments.. voices.. separation.. musicality.. I does everything very well and all this makes this amp just a pure joy to listen to.

I have to say that this is just my first impression of this amp.. I have not done "in depth tests" with all kind of music yet, and I may never do, as this amp may be too enjoyable to analyze. ;-)


What can I say..? I am impressed! I know that I already said that, but I am not the only one. I played a demo track for a few friends today and they all smiled and they all responded with "does this little thing do that?!"

Me? A fanboy? I guess that I am now. ;-)

Below is a picture of my new amp connected to a iPod Touch (4th gen) with a FiiO L9 LOD connector.
(Can't wait for the upgrade to Moon Audio Silver Dragon V2 LOD - but I have to though..)

Nice impressions nOtEcH!

 


I have a question about the ISP programmer.

  • I soldered the ISP headers onto the C5
  • I attached the female end of the pocket programmer to the ISP header pins
  • I tried to go through the suggested downloads and workarounds for Windows 7 but none of them seem to come to any decisive conclusions and/or the download links for the drivers are unavailable
  • Trying to upload the plain, unaltered code to the C5 from Arduino's software (I have the C5's board selected in Tools -> Boards, I get the following error:

I'd like to just say that I find I don't want to listen to anything else anymore.  Anytime I want to listen to music I go for the ER-4S / C5 combo.  I have other very nice audio gear of different types, but I don't use them anymore as the C5 just sounds better and more neutral.  Mmmmmm.

 

The only frustrating thing about the C5 is not having more time to relax and listen to music. :-P

Just got back from a trip today....c5 was waiting for me. So far I'm pretty impressed. Running a fiio lod out of a 5th gen ipod. I haven't had a chance to try any of my better cans so far...just a pair of vmoda m80's that I use in my portable rig. The m80's highs have never really impressed me, but have been tolerable for on-the-go listening. The c5 has added some detail to the upper registry of the m80's. There's definitely an improvement over running straight from the ipod. I do wish I did not purchase the 90 degree lod cable as it blocks the buttons...

 

 

When I have a chance I look forward to trying this out on the beyer t90's. Hopefully they won't demand too much power.

Heard back from John again today, and i must say again and again, and again-again... JDS labs, and John specifically is an absolute credit to the industry. Both he and Billy (Noisy Motel) have been in constant contact regarding the unfortunate luck i had in receiving one unit from the small batch of anodising mishaps. Both John and Billy have by far the best customer service in a field that in my experience so far, already has a noticeably high bar for customer service. I feel like i should be sending these guys gifts or something, its amazing.

 

Its worth buying something of these companies purely for the experience of dealing with someone who genuinely cares about their customers- true luxury treatment!

 

I sing Noisy Motels praises quite a bit, as i buy there a lot, they remember my name (and even my wifes!) and am always left feeling satisfied and well cared for. But this is my first time dealing JDS labs directly, and i was again blown away. Not many more ways to say that these guys ROCK.

 

Thank you both so very much for going well beyond what was expected.

Billy from Noisy motel is an absolute joy to buy things from. One afternoon him and I had a nice 30 minutes conversation just on a random headphone and music issues. He is not just a sales person, he is actually is passionate about music. 

 

I have bought two other product from JDS production line and never had an issue and their activity and reaction to this issue has been more than fair. Other companies should learn from them.

Woah, I just found a great pairing with the C5. I'm listening to INXS's "The Swing" album and the K 701 pairs quite nicely with the C5 for this album. The slightly smaller soundstange makes the center imaging a bit better/less wide/more realistic-sounding, and the slightly more forward mids sound great for the vocals compared to the O2.
