Which USB Re Clocker

The Ideon 3R Mastertime Blackstar is fantastic unit. Several owners have compared it directly to the Phoenix and preferred the Ideon. I own the Ideon with an Innuos Zen 3 and the combo is stellar. I have owned several USB reclockers from SOTM and others selling for $1000 and under ..... and the Ideon is in a different league. Not cheap however. $3200 retail. But can be purchased for far less with the right dealer.

I had to decide between the Phoenix and Ideon. I wanted to buy the Phoenix as I own the Innuos server, but after much research decided on the Ideon. Both are said to be top tier USB reclockers and you can’t go wrong with either.

I must be honest and share that my past experience with Innuos service has not been good. It took them 2 months, and several of my persistent emails, to respond to a question/issue I was having with my Zen. When they finally responded it was with a short and condescending comment of no help from one of the principles. Not good. That soured me a tad and most likely influenced my decision to buy the Ideon.

Your Metrum Octave does not support DSD files.  The Metrum has a decent USB receiver, but probably not quite as good as those DACS with the latest version of Amanero USB receiver.

If you wanted to improve things, I would go with the Singxer SU-6 with an external linear power supply upgrade.  Both the Singxer and the Metrum Octave DAC have a true BNC connector (which is highly superior to normal RCA digital connectors). You can then get an amazing S/PDIF cable to drive the Metrum.  I use a 2-meter Nordost Heimdall II digital coax.  I have not found anything better.  Though, some of the Black Cat digital cables may also be excellent.

The Singxer SU-6 and linear power supply upgrade won't be a wasted investment.  You can always upgrade your DAC in the future.  The Singxer is really there to make the Innous a lot better. 

I'm not sure if the DAC you have uses asynchronous USB. I believe the company went out of business or is realigning or something. IMO you would be better off using your money to get a newer DAC that uses asynchronous USB which makes the notion of things like USB reclockers superfluous. 

Asynchronous USB inputs on dacs do not render reclockers useless. My experience has shown a great reclocker like the Ideon can indeed improve the sonic realism of a system dramatically even if the dac has an asynchronous usb input as mine. 

Really? How?
OP do not go down this idiotic road. The DAC controls the clock you can reclock USB 5 times between the source and the DAC and the DAC will still control. If your DAC is older and isn't aysncronous then a reclocker might be of some use.
