I’ve had the MSB ProUSB in the store for over a week now. This one was not a prototype, but rather a completed version and one which I purchased.
How does it compare? Like everything it comes down to personal preference. However, I thought it best to have a few customers over for the shootout.
We wanted to compare:
1. MSB Roon Renderer (from wall w/AQ Diamond Ethernet to Renderer)
2. MSB Roon Renderer (from wall with CAT6 to GigaFoil/Keces P3 to Renderer)
3. MSB ProUSB (from wall w/AQ Diamond Ethernet to Aurender, AQ Diamond USB to ProUSB, ProUSB via ProISL to ProISL module in the DAC)
4. MSB ProUSB (from wall with CAT6 cable to GigaFoil/Keces P3 to AQ Diamond Ethernet to Aurender, AQ Diamond USB to ProUSB, ProUSB via ProISL to ProISL module in the DAC).
5. MSB ProUSB (from wall w/AQ Diamond Ethernet to Innous Statement - on demo/loan, AQ Diamond USB to ProUSB, ProUSB via ProISL to ProISL module in the DAC).
6. MSB ProUSB (from wall with CAT6 cable to GigaFoil/Keces P3 to AQ Diamond Ethernet to Innous Statement, AQ Diamond USB to ProUSB, ProUSB via ProISL to ProISL module in the DAC).
7. MSB ProUSB (from wall w/AQ Diamond Ethernet to Roon Nucleus Plus with Keces P8, AQ Diamond USB to ProUSB, ProUSB via ProISL to ProISL module in the DAC).
8. MSB ProUSB (from wall with CAT6 cable to GigaFoil/Keces P3 to AQ Diamond Ethernet to Roon Nucleus Plus with Keces P8, AQ Diamond USB to ProUSB, ProUSB via ProISL to ProISL module in the DAC).
At all times, the cables were:
- AudioQuest Diamond Ethernet
- Cheapo Cat 6 (when feeding the GigaFoil)
- AudioQuest Diamond USB
- Analysis Plus Power Cables on the MSB Select II DAC
- AQ Hurricane Source Cables on the various Music Server Transports.
Speakers for the Testing:
B&W 800D3’s with a pair of DB1D subs
Luxman M900u Monos
Luxman C900u Preamp
AQ Speaker Cables and IC’s
- We played an assortment of redbook, high res and DSD64, 256 and 512 files. No MQA as we were playing off the NAS at all times.
Phew!
Findings:
- We found the AQ Diamond with GigaFoil/Keces direct to the MSB Roon Renderer to be the most transparent, with the GigaFoil/Keces taking out some of the grunge in the upper registers.
- The ProUSB nullified the benefits of the GigaFoil/Keces P3. We could hear a big difference in configuration #1/#2, but not once we introduced the ProUSB (which converts USB to Fiber Optic - ProISL).
- However, it was unanimous that the #5 configuration sounded best overall, but finished second due to the reasons noted below. The Innous Statement had meat on the bones, without any noticeable loss in transparency, and sounded very analog. HOWEVER, two notes:
- The Roon Nucleus Plus in the #7 configuration was incredibly close to the Innous Statement - as in 99 vs 100. The Roon Nucleus Plus allows full NATIVE DSD and DSD512. This gave it the edge for our winner in the shootout.
- the Innous Statement is NOT capable of NATIVE DSD on any MSB DAC (via the ProUSB) and it DOES NOT play DSD256 or above on any DAC (limited to DSD128). This may not matter to some, but the NATIVE vs DoP was a big deciding factor, plus we couldn’t play our DSD512 files. If these things aren’t important to you, than the Innous is a worth considering. But in our configuration, it was so close to the $2498 Roon Nucleus Plus, that it was literally indistinguishable when paired with the ProUSB. I have no doubt it is superior on other DAC’s feeding them straight via USB, but for our tests - going into the great equalizer - the ProUSB, it was too close to call.
Therefore, for all the reasons mentioned above, the #7 configuration (MSB ProUSB (from wall w/AQ Diamond Ethernet to Roon Nucleus Plus with Keces P8, AQ Diamond USB to ProUSB, ProUSB via ProISL to ProISL module in the DAC) was the overall winner.
NOTE: My Lumin U1 was not available for this test. I will be bringing it in and testing against the Roon Nucleus + shortly.
