    My amp (Rotel RB-1582 MkII) accepts SE and Balanced inputs. Freya can feed the amp via SE or Balanced outputs.

    My chain: Technics SL-1210GR [regular RCA] to NuWave Phono Converter [balanced out] to Freya | Gungnir Multi-Bit (I think A2) [balanced out] to Freya

    Right now, I have Loki in there between Freya and the RB-1582, but he'll have to go if/when I give Balanced a shot.

    Here are some specs for the amp:

    RB-1582MKII
    Continuous Power Output 200 watts/channel,
    (20 - 20k Hz, < 0.03%, 8 ohms)
    Total Harmonic Distortion (20 Hz - 20k Hz, 8 ohms) < 0.03%
    Intermodulation Distortion (60Hz : 7kHz, 4:1) < 0.03%
    Frequency Response (± 0.5dB) 10 Hz - 100k Hz
    Damping Factor (20 - 20,000 Hz, 8 ohms) 800
    Speaker Impedance 4 ohms minimum
    Signal to Noise Ratio (IHF A network) 116 dB

    Input Impedance/Sensitivity
    Unbalanced 12k Ohms/1.9 volt
    Balanced 100k Ohms/3.0 volt


    Gain
    Unbalanced 26.5 dB
    Balanced 22.5 dB


    Power Requirements
    U.S. version 120 Volts, 60 Hz
    European version 230 Volts, 50 Hz
    Power Consumption 550 Watts

    For those who know these things (and there's a lot of you here, I'm just not one of you!), do those items w/larger fonts give you any insight as to the benefits (if any for my chain) of going balanced into the amp?

    I'll give it a shot to see if I notice any difference, but I was wondering if those numbers would provide some objective insight before I give it a go and let subjectivity take over.

    I like what Loki adds (or doesn't!), so sonic benefits (if any) from going balanced would have to be legit for me to make any change permanent.

    Thanks!

    If you are using your Freya in passive mode, the higher damping dactor due to higher input impedance with balances inputs might be beneficial. Other than that, it's difficult to say and requires some actual listening and testing.

    Thanks. I do plan on listening with balanced. When I do so, I'll focus on passive mode initially. I'm like a kid in a candy shop.
