It doesn't look too bad on the outside.

I am really happy with the sound. I have been listening for a while now and I think the expense was worth it. A lot of my favorite songs are now in flash memory that may live longer that I do

I do not use HDMI to connect my HDTV. The component video looks just as good to me. HDMI is just a big conspiracy pretending to be a high quality connection.

The HDMI adds an annoying delay every time a file is played since the HDMI has to handshake and encrypt things. This delay cuts off the first note on a lot of songs. It helps if there is some silence at the start of your music files.

If you rip some CDs, use the setting "with gaps" in Exact Audio Copy to add a little bit of silence at the start of the track.

I also noted that my DAC takes some time to lock if the HDX plays a FLAC with a higher sampling rate. I edited some 24-96 files and added about 1.4 seconds of silence to the beginning of each track. That way it doesn't cut off the first note of the songs. It's a pain, but I actually don't have that many 24-96's to edit.

Cool project, nicely done. Thanks for posting it!

How do you control it? How do you get the files into it? Via LAN?

Yes. The Flash hard drive in the HDX shows up as a drive in the "My Network Places" on my PC. I just copy the FLACs over the LAN.

I am thinking of doing this to a Popcorn Hour C-200 along with throwing in a linear PSU if possible and separately powering the hard drive , re-clocking and re-capping and find out where the 12Sis in this machine which it supposedly does have do you or any one else think it would be a worthy project that might be able to keep up with a cMP hardwared and softwared PC

It seems similar in concept to the PS Audio Wave player this thing must have off the shelf parts in it ?

I don't know anyone with a C-200 so I have not looked inside of one. It sounds like a lot of work.

A PC can do a lot more than a Popcorn Hour. What apps are you going to use?

For me, the HDX-1000 meets my needs since I only use it for playing FLACs. Are you going to install a DAC board in the unit connected to the I2S bus?

Default Popcorn Hour C-200

It has a Sigma SMP8643 667Mhz chip in it similar to your HDX 1000 and runs a Linux based OS as I think yours does .

I think it may have been confirmed that it can play bit perfect 16 - 24 bit / 96 - 192 KHZ lossless flac and Wav through a recent firmware upgrade but I am still not 100% sure if it passes through some sort of DSP processing ?

I do not need it to any thing but hopefully output bit perfect digital Wav or Flac
or what ever loss less fromat for that matter .

Yes I would run i2S to a DAC inside it as close as possible the TDA1514A or Wolfson flavor .

Mine runs bit perfect as long as the volume control is set to the default. I use analog volume control after the DAC. I do not use the digital volume control.

Both the Popcorn Hour and the HDX use the same core firmware written by Syabas.

Default Popcorn Hour C-200

So if it runs bit perfect with out any DSP filtering what makes the PC a better
Transport if you were to do classic cd player mods to it to bring the noise down
such as linear power supplies , quality caps , re-clocking , i2S , grounding work , discrete regulators separate hard drive power supply as the cPlay site has done etc etc ... would this not be better than a PC transport as it does not have the main problem as a PC having all that cross talk and dirty power , no fans , and running all that other stuff it has to make it stable , the Popcorn Hour C-200 or HDX 1000 could be something along the lines of a PS Audio Wave player unless that player has some sort of mysterious black art in it that thing can not be that different to a media player can it maybe more optimized ?

Rossi have you not tried typical cd player mods to see if it works , can a sound card and ASIO be that much better ?

Any one please correct me if I am totally nuts if it is wishful thinking or possible and if so how , and if not how are these so different to computers ?

No, PC is not better unless you want to use it for processing, games or other PC functions. The HDX-1000 sounds better than a CD player. I am very happy with the sound.

I didn't replace the switching power supply in the HDX-1000 because I am using it all digital except for the analog video out.. ethernet in, SPDIF out, no real need for a fancy linear power supply.

The HDX-1000 would be great for your use, IF you only need one SATA hard drive and will not add in a DAC board... and IF you already have a good external DAC that you can use.

The Poppy C-200 has room for two SATA and some space for add-in DAC boards and new linear power supplies if you want that.

I don't want a PC in my listening room. I wired in a CAT5 ethernet connection so I have network, cable TV and an antenna. The PCs and cable modem are in my office in another room.

Also, I did my own basement remodeling for my listening room, that's why the drywall finishing looks so bad
