I'm wondering if there was possibly confusion and mix up of DAC resolution and internal processing resolution. Jut a thought. If they are truly running at up to 384/32 internally (all channels, not just 2) then hats off to them for being able to do that because that's even more than the Altitude32 can do with it's i7.
Me too. Could this be like Audyssey theoretically
able to process at 96/24 but in practice 48/24? I looked at the McIntosh MX160 web info, the manual & specs and found zero
reference to a 384khz sampling capability with or without RP.
One would think that if it had that capability in the hardware & software implementation, it would be a widely advertised feature to set it apart from competitors.
Putting my geek hat on
The Lyngdorf MP has 8 DSP's @ 400 MIPS ea = 3200 MIPS total per their web info
An Intel i7 4770K @ 3.9Ghz (can't recall which model i7 the A32 has, so picked this one) = 133,740 MIPS
No matter which model i7 cpu the Alt32 has, its MIPS capability is at least dozens of times the power of those DSP's.
Unless RoomPerfect has extremely streamlined algorithms code-wise (or much more basic in what it does), it's hard to fathom how 8 DSP chips can outperform an i7 cpu.
I remember how Pioneer tauted its MCACC as not downsampling vs Audyssey, but it was only a 9 band graphic EQ'r with no sub EQ
, with some standing wave, phase & group delay adjustments bolted on - not close to all the filters and adjustments Dirac & Trinnov do.
The Lyndorf does have up to 384kHz/16 bit input capability for aiff files only, everything else is limited to 192K. That's not the same as saying there's no downsampling with Room Perfect.
I'd like to see more hard evidence from the companies using Room Perfect. I would think they'd highly publicize this since no one else can do it.
