Major EXOGAL Comet/Ion problems


Five years ago I bought an Exogal Comet to use as a DAC with my Rogue Medusa amplifier. It proved itself an excellent unit in all respects and I was positively impressed with the company's support and helpfulness. A year ago I bought the matching Exogal Ion amplifier (at considerable expense) to go with the Comet and was delighted. (The Medusa was wonderful but I wanted something with a smaller footprint). 

Reviewers have invariably criticized the Comet's diminutive window for being extremely difficult to read and the cheapness of the remote control. Noting these deficiencies, the TAS reviewer Vade Forrester (June 24, 2015) wrote, "I learned the Comet is really intended to be operated remotely from an iPhone or iTouch." My experience was that the window and remote were exercises in frustration, but that the Apple application I downloaded from the Exogal site for my iPad was ideal; I had total control over the unit and the app was a delight to use--very Space Age. For the record, I liked the Comet so much I unloaded my Rogue RP 1 and used it as a preamp. 

All was well until I got a new iPad and couldn't download the application. When I called Exogal I received a somewhat garbled account that Apple was no longer permitting them to use the application. Ditto with Android. After a while they announced a remote control module was being developed and in the pipeline. They sent me an experimental prototype that in my opinion wasn't much of an improvement over the original. On the few occasions I can reach them they say it will be ready in a week but weeks have passed. This is tantamount to having a fancy TV where it is a major struggle to perform a simple action like change the channels! 

Exogal is singularly uncommunicative about this problem. Their website is scarcely used and they seem to have moved over to Facebook. The strangest thing is that on the website they list under "Products" a series of four Vortex streamers, described in detail, that apparently were never manufactured! They don't answer their emails. They say their site has been hacked and various other things. In a rare new posting on their website and Facebook they claim the they have just opened a distributorship in Europe. This raises the question how are the European purchasers going to operate their units? None of this inspires consumer confidence.  

My point here is that when someone spends 7k and above on supposedly elite components they deserve responses and explanations. It is Exogal's responsibility to ascertain that these units are operable as designed. I have to question the business sense of relying on an outside entity like Apple that is notorious for being proprietary. It is totally unbusinesslike not to make a public explanation of these issues with a timetable to correct them. Customers should not have to go foraging around Audigon forums to learn what is, or isn't, happening. 

Now the window on the Comet periodically goes blank (it was never even illuminated). Having 7k worth of Exogal equipment that is extremely difficult to operate, I went and bought a Wyred 4 Sound integrated and a Black Ice DAC so I can actually listen to something without a struggle. The Exogal stuff is in a box waiting for who knows what. I am beginning to think that Exogal is indeed out of this galaxy, but for all the wrong reasons. This is very surprising because a couple of years ago they were exemplary in all respects. I would like to hear from other frustrated owners to see what solutions they have devised.

@damianhl incredible stuff! I too agree that the Exogal Comet Plus has perhaps the most natural timbre of any DAC I’ve owned. The mids are simply beautifully depicted.

I spent some time not long ago probing the Bluetooth chip output in my Comet, trying to understand the pulses it sends to create a directly wired replacement. My one gripe with the DAC is its UI - the remote and the android app I run on an old phone have proven to be unreliable and quite slow. 
 

I’ve considered replacing or piggybacking off of the Bluetooth receiver with an Arduino or RasPi, either to have directly wired physical controls or to create a web interface for the DAC. Any documentation or help would be greatly appreciated. Thank you for helping keep this DAC alive!

If those among you who like the Comet are out on the West Coast why not send one to Amir at Audio Science Review for testing? That would be a real contribution to this subject. It would be extremely enlightening to put this unit to the test and determine if it is objectively makes the grade.
