  1. I hear you. I had been going through 30-plus years of upgradeitis (tweaking, trading, upgrading) using the 'traditional' audio setup (digital source, pre/power, passive speaker) and systematically moving up whenever possible. Then I heard the Grimm system (MU1, LS1be, SW) at a Dutch audio event and I was hooked. I first moved my digital source to the MU1 and then, when an opportunity for the LS1 system presented itself, sold my pre/power and speakers (and footers, cables, etc). I have not looked back since. For the past 2+ years, I have just enjoyed my music. One more possible upgrade would be upgrading the LS1 to the top of the line LS1be, but for that I can wait while I enjoy my end-to-end Grimm system...
  2. Quick question: where did you position the PhoenixNET with regards to the MU1? Outbound traffic to the dac, or inbound traffic to the MU1 (if using a different Roon core or external has storage), or both?
  3. I rebooted the MU1 and the update option showed up. I started the update to 1.5.5 (from 1.5.1) and the display at first showed the 3 dots scrolling. Then it froze with 2 dots lit and hasn't moved for 10 minutes... Did I just brick it. How long should I leave it before doing a hard reboot? Never mind. As I typed this, it continued the update :) Me and my lack of patience...😁
  4. Mine is on 1.5.1 and says it's up to date...
  5. Let's see what has happened since 2007 (strangely specific timeframe, but let's go with it) - digital audio reproduction (streaming, DSD, DXD, ...) has come along in leaps and bounds, offering BOTH high-end solutions (DCS, Grimm, Aurender, etc...) and budget / affordable solutions. - vinyl reproduction has had a complete resurgence with both high-end and budget reproduction equipment (turntables, cartridges, phono preamps) - speaker development has come along in leaps and bounds, offering quality speakers from $3000 to $1M-plus And this is through 2 major recessions and a couple of inflation-driving wars, all since 2007. My point is, there is good (or even great) equipment to be had at a wide variety of price points (much more so than 30 years ago). At the same time, there will always be people able and willing to buy Magico M9 speakers and Wadax DACs. The day there are not, people will stop making them, simple as that. No need to get panties in a bunch over material cost of 1 (highly rated) box...
  6. Assuming you're right (and I for one do not think you are), then the market will correct itself in the next 10-15 years when the 'old white dudes' remove themselves from the market (by exiting the hobby or by dying).If you are correct, the demand for these high-end devices should collapse by itself when the iphone/spotify/earbud generation takes over, who wouldn't know good sound if it slapped them across the face, nor do they care. The thing is: this line has been spun by people like yourself for the past 30 years. And the high-end market has never been larger, more varied or healthier. That means one of two things: there is a healthy supply of new old white dudes to backfill the ranks or you are fundamentally wrong in your perception of the high end market. And even if you were correct on your BOM cost analysis (which again I think you are severely underestimating), there are a LOT more elements that go into costing / cost amortization of a high-end component than merely the component purchasing cost. There IS a degree of overpriced snake oil junk on the high-end market and a sucker with deep pockets will easily be relieved of his money. But the bottom line is: the market will always correct itself and vendors will charge what the market will bear. If Grimm manages to sell everything they make and more (back-orders are not uncommon), they have no reason to lower their prices.
  7. I take these statements about the 'obvious sonic disadvantages of Roon' with a grain of salt. Either my ears are not sophisticated enough to be perturbed by this supposedly inferior sound quality, OR there is something else going on. I'm somewhat reminded of the conversations between wine connoisseurs when discussing a 200$ bottle versus a 2000$ bottle and waxing lyrical about the details. A lot of it is subjective and by definition unscientific and personal. I have been streaming for 10 years across a wide variety of hardware (streamers, DACS, streamer/DACs, ...) from Cambridge and Oppo via Auralic, Hegel and Devialet Expert pro. I am also an early adopter of Roon, with a lifetime subscription when it was still only 500$. This was after years of trying to get JRiver to do what I wanted it to. I was a textbook case of audiophilia nervosa, reading all the magazines in 3 languages and always on the lookout for the next big thing or the newest tweak. Then I discovered Grimm. I moved to an end-to-end Grimm-only system and I have not looked back since. Now I focus on listening to music and I hear nothing wrong with Roon. So like I said: either my ears are just not good enough, or Eelco's statement is correct, that Roon is bit-transparent and the MU1 is as well-isolated against interference as it can be made to be within the confines of consumer engineering. To those of you who hate Roon so much: why did you buy a device that can only play Roon, when there are so many other high-end options (Aurender, Lumin, Merging, etc....) to choose from?
  8. That is how I use my setup. I have a corei7 fanless NUC to run Roon ROCK, with my library of 32000 albums on a NAS. The MU1 is working as a Roon endpoint and feeding my Grimm LS1/SB1 system. Very happy.
  9. In an all Grimm system, my understanding is that the MU2 (or at least the built-in DAC portion, which is what sets it apart from the MU1) is redundant. And FWIW, @aangen and @FredM : I totally agree. I have been chasing that Audio dragon for 45 years now and had most of the current 'mid' high-end brands in my system at one point or another (Thiel, Martin Logan, Bel Canto, Devialet, Marten, Mark Levinson, etc...). That all ended as soon as I got the full Grimm system in my living room. I barely look at the 'classic' hifi magazines anymore and just focus on the music...
  10. Fully agree and thank you for clarifying further. Talking to Grimm with the serial number, once you have your eye on a MU1, is the best way to go, especially if SPDIF is a requirement.
  11. To be clear, 1.3 etc. refers to the software (firmware to be precise) of the MU1. Since then, there have been several updates to said software (we are now on 1.5.1 ). Just make sure that whatever MU1 you buy, is capable of running 1.5 or 1.5.1 and you'll be sure to get a model with current hardware.
  12. @Fourlegs : My understanding (as a use MU1 owner myself), is that there have been minor hardware evolutions over time (some minor components switched out with updated versions) but nothing that should impact the proper functioning of the MU1 or differentiate that functioning from a newly bought one. The best thing to do, is get the serial number from the seller, as well as the current firmware it is on and contact Grimm support. They can tell you the device's full history, as well as which components might be upgraded/updated if any. Mine needed a new internal memory card installed, as it would not update from firmware 1.2 to 1.3 (it is currently on 1.51 without issues).
  13. Thanks Eelco, I just truned it off and music still plays. I have no idea what may have happened, but all is well again :)
  14. As far as I can tell, the system plays native DSD up to DSD128 (limitation of the DAC in the LS1), but I will double check the signal path tomorrow morning at my next listening session. And I can also compare it to what it does with a DSD256 file.
