This is a very interesting discussion to me… I´ts been more than a year, since I became a happy Lumin T2 owner. I would like to share my honest opinion, with no intention to offend or try to mean I have the absolute truth. Just my thoughts after spending a considerable time with the T2.
As Robert points in his post, the T2 is fantastic, and I also agree there is no disappointment since the T2 does very well.
That doesn’t mean that the T2 is Perfect. There are a few things that could make the T2 much better (hopefully could be added with firmware updates). Other things, I guess are part of the T2 architecture and will remain.
The best of the T2:
- Seamless integration to Roon
- Upgradable via updates
- Very good Native app
- Solid Construction and finish
- DSD 512
- Excellent dynamics
What Could be Better (Firmware update):
- NAA Compatibility
- The capability of choosing different Filters
- 705.6 & 768 kHz PCM Sample rate capabilities look to be restricted via Software and not due to any hardware limitation.
Lumin T2 benefits a lot from good upsampling, when playing redbook 44.1/16. To my ears every time I don’t upsample 44.1/16 PCM in the T2, the sound is edgy, kind off harsh and a little bit sibilant (mostly in the 8k band) compared to the times the t2 is playing upsampled music via ROON . Perhaps the ESS noise shapers and filters are the bottleneck of such a good Lumin implementation. ( Internal hardware upsample is below the overall quality of the product. not really an option if you use ROON)
DSD is a whole different story, the T2 does an incredible job playing any Native or Upsampled DSD.
I’ve tested it in my Speaker Rig (MA8900 +Sonus Faber Sonetto III), and a couple of HPA setups with The 4XX, 6XX, Verite Open and Aeolus HP.
So I just wonder why Lumin is not taking seriously into adding NAA capabilities, that could take the product into another level when using HQ player.
Not surprised that there is people thinking of getting a Spring 3 or May… I am heading in the same direction of having a different flavor and exploring a different approach of D/A conversion. That does not mean the T2 lacks SQ. Is just that when you hear the R2R sound, is evident there is another way with a different sound signature. Why not having the best of both worlds.
Please LUMIN add NAA Capability
