I wanted to get this out last week, but forum drama, and my kids brought back the flu. Kids were fine but their mommy got knocked out for two days. I'm been hanging in here with some good days and bad days, with good days meaning I'm on Red Bull and Ibuprofen. I didn't want to wait any longer, so I decided to take some basic measurements just to give myself a jump start. This will be one of those stream of consciousness reviews. ZMF Auteur Classic @zach915m: Can you clarify what wood and what pads? Or at least what the standard pads are that come with them? Pretty sure with the FR below that I am using Auteur pads. ZMF Auteur Classic Frequency Response Like the OG Autuer before, the Auteur Classic is the most "neutral" sounding of the ZMF lineup. The Atrium is bassy, the Verite Open is laid-back, the Verite Closed maybe a bit midcentric, but these three are rich and full sounding. The OG Auteur had been said to be somewhat HD800 sounding (well not that bright, but you get the idea). The Auteur Classic is somewhat like the HD600 of the ZMF lineup. Because my JAR600 are out on loan, I've been using the Atrium and RS-1X (Gerod pads) recently, so it took me while to acclimate to the change. I found the timbre in the highs slightly artificial while using DS DACs, but a switch to a multibit DAC fixed this. With respect to technicalities and scalability with better upstream components, the Autuer Classic is behind the Atrium and Verite. It's not far off though. This seems appropriate given its about $1k less. Depending upon the recordings one listens to, this may not matter. (I feel a good discussion on source first, amp first, or transducer first is warranted because a lot of this will depend upon the recordings one listens too - and of course one's experience and budget). Now getting back to the HD600 reference? Well the Autuer does share the HD600's small bumps in the presence region and midbass. The lower-mids aren't emphasized so this contributes the clarity aspect. Finally, transient response is somewhere between Atrium and Verite.
