    More detailed Technical Specs

    I've noticed that Logitech isn't as detailed in their spec on the Touch as they are on the Classic. For example, the Classic spec page has details like:

    High fidelity Burr-BrownÖ 24-bit DAC
    Two dedicated linear power regulators for DAC and line-out stages
    Full 6.0Vpp line-level signals
    Signal-to-noise ratio: over 100dB
    Total harmonic distortion (THD+N): less than -93.5dB (0.002%)
    Digital S/PDIF outputs
    Optical and coax digital connections
    Dedicated high-precision crystal oscillators (no PLL, no resampling)
    Standard IEC-958 (S/PDIF) encoding
    Optical connector: TOSLINK 660nm
    Coax connector: RCA, 500mVpp into 75 ohms
    Sample rates: 44.1Khz, 48Khz
    Audio format: linear PCM, 16 or 24 bits per sample
    Intrinsic jitter: less than 50ps (standard deviation)
    Headphone output
    Standard 1/8" jack also functions as an IR blaster
    Minimum headphone impedance: 16 ohms
    Total harmonic distortion: less than 0.03%
    Left/right crosstalk attenuation: 92dB

    So, given that the Touch supports 24/96 playback, this is probably a stupid question, but does anyone know how the Touch will compare? Not that I could probably tell if it was any worse, but I'm blown away by the sound of my Classic, and I'm foaming at the mouth to upgrade. I just don't want to give anything up.

    Thanks!

    Good question

    Good question. I was asking myself the same question. will the sample rates of up to 24 bits at 96 kHz add anything in the audio quality compared to the Duet receiver?

    I'm little concerned that the "24/96" means it supports it through SOX and may not be native. You know those Marketing guys how they like to stretch the truth. It's great is true though. Seems to me they will not sell any more transporters if true though.

    According to a tread in another forum, it has the same DAC as the Transporter so should support 24/96 natively...

    what basis do you have to think Logitech would be disingenuous?

    I don't share your cynical perspective that Logitech would try to pass off 24/96 support with SOX. If that were the case they would be already claiming that the Classic and SB Receiver support 24/96.

    I also question whether the SB Touch will take market share from the Transporter, they seem to me to be well delineated. The Transporter has features that audiophiles are looking for e.g. balanced outputs, rack mountable, appearance.

    If it's the same DAC as the Transporter, I will be over the moon. That's assurance enough for me that I'm not giving anything up in the new device.

    It's native. The hardware supports 44.1k/48k/88.2k/96k without re-sampling.

    I'm about 90% sure it isn't the same DAC as the transporter.

    Only repeating a prior post. Nice to know it does 24/96 natively...

    Will the Touch pass 24/96 through its digital outs to an external DAC? I have a DAC capable of 24/96 but no such sources. This would be cool! Thanks.
