US spec sheet is up: HiFi ROSE
Differences:
150’s Dispay IPS vs 130’s Display TFT 14.9in / 15.4in
150’s CPU = 130’s CPU
150’s GPU = 130’s GPU * T864 / T860
(Mali-T860 is a configurable product which chip manufacturers can size to meet their needs. Mali-T864 is a 4 core Mali-T860. Note that Arm’s official name for this would be “Mali-T860 MP4”, but some chip manufacture datasheets use the short-hand Mali-T864 name)
150’s Memory LPDDR3 @4gb vs 130’s LPDDR4 @4GB
150’s has no cache vs 130’s NVMe SSD 256GB
150’s ethernet standard interface vs 130’s SFP (150 can externally get same feature w/ FMC conversion kit)
150 has no clock input vs 130’s 75/50 clock input (Debatable Feature as most high end DAC’s have external word clock inputs)
150 Voltage controlled femto internal clock vs 130 oven baked clock 0.38 / 0.3 PPM (virtually identical)
150 Fuse T3.15Al / 250v vs 130’s 6A Thermal Circuit Breaker
150’s Storage Interface:
USB3.0x2, micro SDx1, SSDx1
130’s Storage Interface
USB3.0x2, SATAx1, USB 3.0 Fiber
(No internal storage for the 130 except for the onboard 256gb SSD, I could be wrong as they do reference SATA but no donation to location)
Per the marketing message from Rose the 130 is superior to the 150 due to Fiber isolation for the ethernet signal, USB fiber isolation which reduces noise further, Oven baked clock for increased audio timing / synchronization, linear power supply with high capacity super capacitor and word clock inputs for external master synchronization. I will leave the display features open to your opinion as I view that spec as a downgrade. (I guess this is the value proposition).
The one major issue I have is the discussion on the upgraded Linear Power supply is implying the 150’s LPS is inferior and without super capacitor. The 150B does have a high quality LPS with super capacitor.
I am sure there is more that I missed but these are the obvious ones…
