    One thing I noted in my review is I was incredibly impressed by low volume performance from this amp, perfect candidate for lower listening setups. Was able to listen much lower than my aegirs for satisfying performance.

    Great point. I kinda think if an evaluator can do low level, then I can definitely agree it's very valuable point.

    However, I know I'm extremely poor at doing that. Here are some of my shameful failures.
    • I couldn't discern Vidar vs AHB2 at 70db spl (at listening point) or so. Even in the sighted listening.
    • I've failed to tell apart between single vs double aegirs at 70-75 db spl in the blind testing.
    • Freya S and Jot 2 (as a preamp) sounded almost same to me around 75db spl.
    My analytic listening via headphones typically done at 80-85 db spl at peak. And I believe everything not BS sounded more or less similarly good at low level. I may call out something terribly bad. But this loaner doesn't look like the case.

    Wanted to extend our thanks from The Factory - I am enjoying the journey with all of you here... and we will for sure be offering several new products in the near-future.

    Many thanks

    Not to wander too far off topic since this is the loaner thread, but from my understanding, low-level listening tends to highlight a few things. First, most tube amps will excel at this since tube's (generally) inherent distortion profile rises with voltage. Solid state (generally) is the opposite. Lower listening levels place less dependence on huge current swings to control big-mass floppy woofers, too. Second, an amp that does better at lower millivolt/microvolt input levels tends to swing bigger relative macrodynamics. Sensitivity at the .001v-.1v range can be loads more convincing than sensitivity at the 2v-4v range. But I'm no EE, so I'm probably parroting some BS an audio dealer convinced me of.

    I’d like to give it a listen but it will be first week of Nov before I’ll be ready, so please throw me at the end.

    @rhythmdevils you said you're looking for more victims for loaners. I could eval and report back on this amp in 2 specific systems. 1: as the bass amp in a bi-amped open baffle + horn systems. Would be comparing against a cheap Class AB pro amp. 2: as the sole amp in a philharmonic audio-modded B22 desktop system. Would be comparing against a JLH69.

    Neither seem like a "normal" use case for this amp (aside from generally listening at low levels), so I'm hesitant, but if you think the data points would be useful then...

    sure! I’d love you to audition the amp.
