Perhaps a new amp is not what you need to achieve your sonic objective? I remember being amazed when a dealer showed me that everything I thought I needed a new amp to achieve, was actually realized through upgrading the preamp. It didn't matter to him, as he could have easily just sold me a new amp. Before you upgrade, you should make sure your source(s) are not what you need to look into. That being said, I would not approach a system upgrade as a tube v. solid state thing. I would concentrate on finding a sound I liked and not being concerned with the mechanics of how it's produced. If you're looking for a warmer sound with more low end, try placing the Spendors on the floor and prop up the front with a wood block or a book. See if that gets you closer to your sonic goal. If it does, check out the Mapleshade stands. Good luck. BTW, I was using a BADA 225 hybrid with a pair of Harbeths (similar to Spendors) with very good results. Available from Pacific Valve with 30 days money back. Nice amp. $1200, 95 wpc - smooth, powerful sound with excellent inner detail for an amp at this price.
