Looking for a SS Amp to power Spatial Audio X-5's

Thanks all!  You gave me some ideas to start with.  I'm looking at the Chore Ultima series partly because I'm hoping for a good blend with my Dave DAC.  First time I've heard the term "Watt Quality."  I assume you mean the stableness of the flow (Watt is a Watt, unit of measure).

@fixedincome - yes, a watt is a fixed unit of measurement.  However, a high quality 20w amp that suits your tastes will sound a lot better than a poorly constructed 100w amp that doesn't suit your tastes.  In addition, the way an amp clips can make a big difference to the perceived quality.  Tube amps generally create pleasing distortion when they clip whereas solid state amps tend to sound harsh when they clip.

@fixedincome,
What I meant by "quality watts" is you don’t have to be as obsessed with amplifier power as some who own insensitive and difficult to drive speakers. There are some really fine sounding lower power amplifiers available. Your Spatials allow the opportunity to explore this niche of excellent amplifiers

I’m not that familiar with this speaker so perhaps a 5 watt SET may or may not work, but amps in the 15 to 50 watt range certainly could. For example I believe that the First Watt S.I.T.-3 could possibly be an outstanding match.

@mikem,
Thanks.
It brings back pleasant memories of 20 years ago driving from driving from Phoenix to Grand Canyon AZ. I was listening to the Ella and Louis Armstrong CD set. Entire family in the car enjoying the music and scenery.
