JDS Labs C5/C5D (pg96) portable amp/amp+DAC appreciation + discussion thread - Page 59

post #871 of 2684

Can someone recommend a good 3.5 mini cable (<$50, preferably <$20-30 if possible) to connect a C5 to ipod touch 5.  It seems the lightning adapter -> LOD would be too much cable-age and I'd like to keep it as minimal as possible.  I wish I could build the cable myself as I've seen in other posts, but as a medical intern, the free time i have i'd rather sleep or spend time with family.  Appreciate your help!

Are you looking for a 3.5 to 3.5 cable? JDS sells those on their website under the cables section. It would be best if you clarified a bit on what you would like.

Guh, that new Lightning Adaptor has created chaos in the audiophile world. I don't know of any reasonable solution to having a shorter cable except for maybe....nope never mind, it's an overpriced $50+ USD cable.

 

As Thlayli said, you could just use a 3.5 mm to 3.5 mm cable. It doesn't bypass the iDevice's internal headphone amplifier though. Maybe a FiiO L2 or L8?

'Hey Thlayli, sorry about that, yes I'm talking about the 3.5 to 3.5.

Thanks miceblue...I am definitely hating this new lightning connection.  Even on my car stereo, the new ipod requires additional cables and therefore, more $$$.  So frustrating.  

 

Is there any difference silver and non silver (i.e. Fiio L2 or L8) 3.5 interconnect cables?

That's probably to improve click and pop performance.

You can just use a regular 3.5 -> 3.5 cable.

 

The iPod Touch 5 (I'm assuming this is what you mean by "iPod 5") has improved a lot in quality, so double-amping is not as bad as it seems.

Try this it's 10cm long,

or this bit shorther around 8cm long.

Both are nicely build and will fit your budget nicely.

The volumer-clicker was real fun to mess around with on the C5.

The C5s were impressively clean. Could use a bit more treble for my tastes. Just clean, flat for the most part, good punch and nothing audibly wrong with them.

For a second I didn't even realize it was on as I thought I had the Annies on instead of the Qs (explains the messy cables). Then I realized I had the Qs on.

So from that I can gauge that the Annies basically have a similar boost as with the C5 boost on the Qs. Otherwise they're so identical I got confused.

^ in other words, the bass boost is quite effective for the K 701/Q 701, and I agree with that.

 

I don't know what JDS Labs did for the bass boost, but I really love it, hahaha. The E12's bass boost sounds more like a narrow mid-bass boost whereas the C5 has more of a wide sub-bass boost. I find the C5's bass boost much cleaner-sounding than that of the E12 based on today's mobile listening sessions.

Yes I too would be in agreement for the bass boost pairing of the C5 and K701 and it is quite effective with certain kind of music that does'nt have bass in it as I just find the instrument more pleasing to hear like the impact of the lower notes on a piano or the guitar strings being pluck or strum...they just sound much more fuller that way.

On another note and since I'm still awaiting for my thermistor to arrive to test it out on my S3 battery mod and have really nothing better to do biggrin.gif, I'd thought I'd just post the total playback time I get with the S3 battery(with the C5 battery board transplant).

Once I get my thermistor I will try and test if it's and easy working mod and worth the hassle or not and if it's working I might even post a how to later on.Wish me luck.

Well coming back to the C5s, I'm wondering should i get the ODAC and C5 combo. Or am i better off using O2 combo. my main issue for this is mobility and durability. I'm carrying everything in an attache case so major damage can be avoided, but small bumps are unavoidable. I don't want to get something that would be too fragile for constant carrying.

Attache case....like James Bond?

ODAC/C5 combo sounds good and is more portable. ODAC/O2 sounds better but is less portable.

 

ODAC/O2 as a combo unit would probably sustain less total damage than the ODAC/C5 as separate units.

 

All 3 units are pretty durable, but I feel that the C5 and ODAC's smaller form-factor make it more durable. I would be less worried about dropping my C5 and ODAC than the O2.

Mine is not a zero halliburton but i got about a 4 in aluminum case. i have 2 in left after putting in my laptop. i'm guessing ODAC would be too big. unless it's got a 4 width cause i can fit something next to my laptop since i only use 15 in of the 17 in.

Output impedance (slightly different from the original measurement of 2 Ω):

The battery life specs have also been updated:

I still find disagreement with the battery charging time though (it takes approximately 2.5 hours to charge my C5 from dead to fully-charged from the two times I tested; unless the charging LED turning off doesn't really indicate the battery is fully-charged):

The firmware for the C5 has also been slightly updated (v1.0.4 or v1.0.5 now):
It looks like the main change is the delay for the C5 to turn on and stabilise

Is the firmware in the C5 user-upgradable?

Yes, if you have an ISP programmer and 6-pin header.

 

The firmware changes mentioned above do not affect performance. In production testing, we found that 2% of C5's could not boot properly due to [exceptionally] above average capacitor values on the supply rails. Longer boot delay enables proper booting for every C5 we've tested to date.

 

Summary: Firmware upgrade is not necessary if you already own a C5. Every unit is tested.
