Cool thanks again for the info.  The WaveIO (http://luckit.biz/) I use is galvanically isolated, but I'm not sure if it is reclocks afterwards.




By the look of it that is not the case. The isolated OP is coming straight from isolators sans reclocking - as far as I can see.

Got a reply from James from Line Magnetic about my query regarding if I could replace the xmos based usb interface in the LM502CA with another unit like the JLSound I2SoverUSB.

His reply follows:

Hello Tuyen,

Thanks very much for your inquiry. However sorry to inform you that the USB module cannot be replaced by your JLSound module.

Please check.

Thanks and with best regards,

James


His reply was sort of what I was expecting coming from the manufacturer.  Was just wishful thinking...     

Reality is, I'm quite confident it wouldn't be that difficult to replace the stock usb module with another one like the WaveIO or the JLSound I2SoverUSB. From the close up photos, I can only just see the 4 I2S wires coming out from the stock module going into the DAC mainboard.  Assuming it is USB powered as I don't see a dedicated 5v line coming from the power supply section going into to the module..         therefore even if the dac does not support higher sampling rate than 192khz or direct DSD, even replacing the stock USB module with a different one that allows for dedicated external 5V input instead of using USB power, would bring noticeable improvement in sonics.     Just my personal tip for current/future owners of one of these LM LM-502CA DACs and plan on using it's USB input!   :-*

PS. I could be wrong too. I hold no responsibility if you attempt the following and cause damage to your DACs!  :P

Mark, where did you buy your new DAC and how much.
Hi Steve, Graham bought both of ours via AliExpress for just under $1k each. Bargain! I believe these will be 240V versions.

Cheers, Mark.

Is this the one you guys bought?

http://www.aliexpress.com/store/product/Line-Magnetic-Li-magnetic-LM-502CA-digital-audio-decoder/1026221_1639921542.html

I see the same seller has another one listed for nearly $200 less delivered, did you ask what the difference is?

Hi Omodo, Not sure why there would be a pricing difference. I simply asked Graham to tack my order onto his existing order,...he's usually a pretty "savvy" buyer. I only stipulated that it should be the 240V/50Hz version.

Excellent, I'll get to hear it.   :D

Steven will change it further to dial it in for his system.

The reports I have read thus far have been using cd transports.    Whose using a computer source,,, anyone?

Well the verdict is in on Bryans much modified Line Magnetic LM-502CA Dac. All had a similar tale to tell, First the standard Line Magnetic LM-502CA Dac. On sound quality is the standard Line Magnetic dac worth buying,  universally the verdict is the standard machines are only good to OK sounding, some hardheads thought they just aren't good enough, but considering the $1000 price tag they are very tempting, As to the question, on a well tuned wonderful sounding system is Bryans much modified Line Magnetic LM-502CA Dac a killerdac killer, They clearly say NO. I think on any given system in various states of tune any DAC can appear to be the best, but eventually over time the answer is there.

Interesting.    I'm assuming these comparisons are using 16bit sources?   (CD transport)
