Spatial Audio Raven Preamp

What Lynn said about coupling caps is true.  I have gone through most of the best ones in various designs, and they can sound good to very good.  But the entire Revelation series we designed for Spatial has NO coupling caps from the input to the preamp to the output of the 300b amps.  When you eliminate all of them the sound is quite remarkable.  Provided you have REALLY good custom transformers, specifically designed for their application, and we do.  The Raven preamp will actually drive a 600 ohm load, so a 5K power amp is nothing to it.

I placed my order 2 weeks ago and chose the cherry base.  The build should be complete by the end of May according to Spatial.  I will post my impressions after about 20 hours of burn-in.

@jc4659  Yes, please do.  What amps and source(s) are you planning on using with the Raven?

@donsachs Hi Don. Initially the Raven will be paired with a Pass Labs X350.5 power amp.  At some point I’ll need to downsize the amp but ithe Pass drives and controls my Verity Audio Parsifal Encores very well. The analogue side is a Linn lip-12 with a rebuilt Troika MC cart into an Ayre phono pre.  On the digital side I stream or play files from a MacBook Pro running Audirvāna and Qobuz which feeds a Musetec DA-005 DAC.  CDs are spun with a Meridian 508.24 used as a transport only. While I will likely make additional changes elsewhere in my system I am hoping the Raven preamp will be an end game component.  The Raven will be replacing an Ayre K-1xe preamplifier which is itself very good.  Overall, I would characterize my system as slightly on the warmer side of neutral.  I am wondering if the linlai tubes in the Raven might be a better fit.  Open to suggestions.

Yes I think I would try the Linlai tubes.   Your system is fully balanced, so the Raven should shine there.  Please do post a review when you have put a few hours on it.
