Do I Need a Dedicated Streamer?

Re: Mac Mini, it depends on what you need.

First off, keep in mind that you have a streamer built into your amp. There's no need to buy another box to get streaming capability. If you need more info on how to best use it, I suggest contacting Hegel to get their advice.

Here are my thoughts:

If you only want to stream from Apple Music, you're probably better off just using AirPlay and your iPhone. Adding a Mac Mini would only complicate matters in terms of remote control. Also note that the Music app on macOS doesn't perform automatic sample rate switching. Instead, it will resample the audio data to whatever is set in the Audio MIDI system app.

If you have music files stored on the Mac Mini that you want to playback on the Hegel, I suggest installing a free program called Kodi. This will turn the Mac into a UPnP server with the Hegel set as the client (or 'renderer' in UPnP speak). You can control playback using the Kodi web interface or from your phone using a remote control app called Yatse. There's no need to directly connect the Mac to the amp using USB - it will stream the audio data over your local network. See the links below for more information.

If you'd like to try another streaming service such as Qobuz or TIDAL, I suggest using the mConnect HD Player app on your iPhone. Tap on 'Play to' in the top left corner and select your Hegel from the list that appears. Then tap on the music service and supply your username and password.

@danby99.  You've got great gear.  Streaming from you computer is your weakest source.  You have invested $$ into your system, just spend some more to get the best results.  

I am using a PC for streaming, mostly due to budget constraints. The PC is hooked to the router/modem via ethernet cable. The PC sends the stream, via USB, to the internal DAC of the AMP (Cambridge Audio CXA 81). I have also installed a jitter filter between PC and AMP, which helped considerably. I am using an Audioquest Forrest USB cable and plan to purchase an upgraded LAN cable. 

I know this is not optimal but it's still better than streaming from my iPhone via Bluetooth, even though my amp does a better than average job. The PC can also stream FLAC files, via Amazon HD, My Bluetooth is limited to 24/48, which is still CD quality plus.

BTW, thank you yage for the links. Very helpful.

I'm a H590 owner and will get right to my points.

You have the bones for an awesome system but have to get a decent streamer.  Right now you're driving a Shelby Mustang in first gear only (there are 5 more upshifts).  To realize the full potential of the KEFs I would look for a streamer $2k and up.

I would forget USB out of a mac mini into the Hegel, the jitter will compromise what the rest of the system can do.

Hardwiring (no wifi) will be superior to keep the noise down.  I even went to the length to remove two network switches that were splitting signals and when to a home run from the router directly to my streamer and got a noticeable improvement which was a very inexpensive upgrade.  Many of the dedicated high end streamers don't even have a wifi option and they do it for a reason.

I personally run Isoacoustic feet on my speakers and subs.  I have a floating hardwood floor and the aftermarket feet are worth the investment esp. for the subs.  If you have hard floors give them a try.  Not sure what the result would be  over carpeted flooring.  Maybe another user could advise us?

Bottom line is you have a fantastic system and a $2K+ investment in a really good streamer IMO will bump up your SQ by 20% or maybe more.  Airplay is your weak link.

If you want to try the shallow end of the pool--first try Tidal connect with a free trial.  Tidal connect is HQ audio, similar but different to the high rez Apple music option.  Connect your H590 directly to your network via the Lan port and once your Hegel is on your personal network you can bypass airplay and play Tidal connect directly from your network.  This will be a OMG moment where the soundstage will get wider, deeper and the bass will be MUCH cleaner.  Good luck and cheers.
