Did you try a reset on the classic? Hold play button and center button.

I just did and for a moment I got excited as it seemed to work fine for a few tracks but then started up again.  I think I will check my iphone again to confirm that it's the ipod and not the CEntrance.

 

I sent a pm to "mgoodman" but haven't heard back yet.   I am suspecting that it's the ipod at the moment though.

With all the raves and continued success of HiFi-M8, truly am surprised mine has lasted weeks in the For Sale forums without being sold.

if I reduced the price by $20 for the next couple days would anyone here be interested?

I'm trying to get a handle on the compatibility.  As a long time ipod user, I haven't really looked at other players and always looked for dac/amps with the ipod in mind.  The more I look though at the options that would allow better quality as a source I wonder if the Centrance is limited to iDevice, A&K, and computer?

 

And since I have the iDevice model I would have to get rid of it to find an LX model.

Android is also an option, as it inputs the same as you computer.  The Sony ZX1 has been on my radar, and would work with the "idevice" models...

The Hifi-M8 is also compatible with some Android products.

Also a member seems to have got it working with Fiio X5, bit of a jumble of cables though.

 

 

 

Also look at the Centrance upcoming Mini-M8 thread. It has many input variations/options.

I was kind of hoping that I could do something like the A&K through the usb port but if the ZX1 works that way then that would work fine since I'm using the dac/amp of the CEntrance anyway..

 

The Mini-M8 won't work as I am using this with the HE-560s.  I know, I know... but it's not for outdoor portability, just I work at home and have a couple workshops that I need to move between for some of my listening.

Anyway, I am enjoying it but have a couple questions.  I'm running mine with an ipod and when I switch albums, it takes about 3 secs for the sound to start so I am constantly having to start the first song over again.  No problems once it's playing an album but a bit annoying if I want to move around and listen to tracks from different albums.  Also, I've had to turn it off and on again when first powering up as a couple times there is no sound..  Is this normal behaviour?  I can live with it if it is but I wanted to confirm this.

 

And... until I started reading this thread, I didn't realize that the XLR output is no different, just a different plug than the 1/4" SE output, correct?

I was just about to buy a new cable with an XLR plug to see if it would be different... I guess there's no point then?

 

Did you turn the gain up high? It seems fine with my Audeze cans but I don't know what the sensitivity of the 560s are.

 

The balanced output is connected to a balanced circuit, where both the positive and negative have amplifiers driving them. A normal amplifier only has drive on one side, ie: the positive. Some full-size amps have 4-pin XLR sockets for convenience for people who have headphones that are already terminated that way, even if they aren't a balanced design internally. However, I'm pretty sure the M8 uses a differential (balanced) amp internally.

I heard the @CEntrance #HiFiM8 at Capital Audio Fest.  I am very very impressed by the sound.  I may have to get one.

That's a little insulting..haha:tongue_smile:  Yes I did have it at full gain and on one album, max volume and it was still at decent listening levels.  The strange thing with the HE560s though, (and I'm not alone in the observation) is that after some "burn-in" I could run it at lower volume.  I've never encountered that before.  That same album at max gain and volume is now on max gain but about 2-3 o'clock.

 

I think the choice of the word "power" might be wrong and I should have said not enough gain..  Anyway, I'm happy with how it's sounding now even if there's the odd album that could use a little extra gain.

 

I still haven't sorted out the ipod issue yet though.  Not sure what's up with that.

 

As far as the rest of your comments, here's post 4913 as suggested above and why I wrote what I did: (unless I misunderstood)

Great find, thanks! If memory serves right, this is about the time (Fall 2012), still during the design phase, when we actually switched from a fully balanced path (yes, we had a version like that in the beginning) to a different circuit topology, with a single-ended, but more powerful amp and an impedance-balanced output. I still have the old PCB somewhere and can show that we did in fact test that fully-balanced version.

The reason we eventually switched was battery life. We had to make a compromise and give you both high output level AND relatively long-lasting battery. We achieved both with a design technique that was a good choice (and judging by customer satisfaction it still is a good choice today, on the sound quality level, aside from the verbal controversy.)

The reason I never got into the argument about balanced headphone cables was simple. There is a small army of devotees out there who DO hear the difference. Possibly due to RF protection offered by balanced output. May be they live in a busy metropolitan area with much cell phone interference and M8 filters that out well. Or may be because their recabled headphones offer a better balanced impedance in the send and return wires. We can only guess at the factors now, but people have written in to say that the balanced output worked for them.

Whether or not there is a huge difference is not my place to decide. I provided the feature without questioning why. If we start questioning the real delta difference between having a feature or not, let's ask if anyone has seriously benefitted from re-purchasing their music collection in full 192-kHz glory. Would it be my place to argue that the benefit there is small? Of course not! Not my business, but the business of the customer to make that call. I deliver the tools, not the taste.

Having said all of that, a sneak peak to let you know that the upcoming Mini-M8 actually does drive the balanced output with a dual amp. Not as powerfully as HiFi-M8, so we could both use the dual amps AND extend the battery life to 11 hours (Mini-M8 is designed to be used mostly with IEMs, so output power is smaller than HiFi-M8, which will continue to sell and power all big cans). So with Mini-M8 it will be truly possible to hear the difference between a balanced driver and a single-ended one. And yes, the balanced jack will have about 6dB more sound level.
