Edited June 17, 2024 To better described AVM 90 as Stereophonic Prepro.
@Boris I just read the HiFi Rose RS520 Website. The RS520 is described as an all-in-one Audio Streamer, Pre-Processor, Power Amplifier, CD Player/Ripper (with use of RSA720), and a limited Video Player.
So, you believe that this RS520 product’s Audio Streamer produces better streaming sound than the RS130 which has Fiber Optic SFP capabilities, Linear Toroidal Power Supply, ‘supercapacitor’ UPS feeds (battery), and more. Hmm! I disagree.
RS520 Pre-processor capabilities is in a much lower league than the AVM 90. For example, AVM 90’s ADC capability uses 768kHz, DAC’s are the same, as previously mentioned the AVM 90 has a powerful Room Correction system which balances up to 9.4.6 speakers for your room’s acoustics – it even adjusts phase polarity of your subwoofers. The AVM 90 is both an impressive Home Theater system & Stereophonic system. It supports up to 40 virtual inputs (each input defines a room measurement (e.g., only one person MLP room focus, or say a group room focus). In addition, each input defines the speaker configuration (e.g., 2.0, 2.2, 5.2, 5.2.4, etc.). With this AVM 90’s powerful room correction capabilities & virtual input focus, many Audiophiles have stated (in the AVSForum AVM 90 Owner’s Thread) they’ve sold their stereo prepro after purchasing the AVM90. Need I say more.
RS520 Power Amplifier is in a much lower league than my Macintosh MC 255 power amplifier & my Anthem MCA 525 power amplifier. Both these amplifiers have proven power management to easily drive 2, 4, 6, 8 ohm speakers.
RS520 CD Player is in a much lower league than my Magnetar UDP900. Just read up on the Magnetar UDP900’s universal disc playback (CD, SACD, DVD-Audio, DVD, Bluray, UHD Bluray, etc) and read its impressive audio capabilities. You’ll see.
I won’t continue any further about your boast that the RS520 is a much better product. I’ll just say, I disagree.
