A bit of positive support for it from me, as I think they look brilliant and the amp will undoubtedly be on my audition list when the time comes for an upgrade.
Items like the M33 don't especially interest me quite the same, they don't seem to resonate Hifi to me, but rather technology. Pure analogue amps like this Model 30 are something that don't really date the same, and I also really like the fact there's no DAC in it. Again for my use case I like to swap kit occasionally and having been well and truly won over by Schiit's Multibit DACs I don't want to 'waste' money on my next amp having one built in I won't use.
