My Music Hall CD 25 just died

If you have any interest in a computer based system but don't want to deal with the complexity immediately a good path might be to get a decent DAC in the $300 range and pick up a used CD or DVD player to use as a transport.

There are always high-quality players from Pioneer, Sony,, Marantz, Arcam and others for sale here at a fraction of their original price.

Going for a DAC now means you don't have to start over completely when your transport fails, as they all eventually do, and gives you the flexibility to deal with multiple sources in the future.

What are the symptoms of not working. Is it not reading a disc and not powering up, or? Its a possibility that it can be an easy cheap fix but most likely its the laser. I am not to familiar with PC based audio so I will leave that up to another.

In answer to your questions:
(1) Definitely do NOT repair it.
(2) Buy something used (but not too old) on Audiogon.
(3) Buy a universal player for CD, SACD and DVD-Audio.
Enjoy the current formats until something better comes along, and it could be awhile.

"Just died". Can you be more specific? Dead, as in no power, no display, no drawer, nothing? If so, it's the power supply, and any competent technician should be able to repair the switch mode supply used in this type of device for $30 or so (time included). Seems sad to toss a piece of gear because of a 30 cent capacitor.

As for the Mac Mini...you can run it headless quite easily (no monitor), and there are free apps available for both Apple and Android phones/devices that will manage the music playback. If you cant afford Pure Music(which runs Mac only), there are others free or nearly free that do a great job as well.

I wont go into a long list of DACS here, but there are many stand alone DACS under $500 that beat the pants off most CD players when fed uncompressed files from a Mac Mini or a PC.

I urge you to strongly consider a move to computer audio..it delivers great digital fidelity, return on investment, and ease of use.
