which pure class A amp to use or 93dB speakers

If you want to try a really good budget option, get a Monarchy Audio SM-70 or better yet an SM-70 Pro. They produce 25 watts/ch. in stereo and are switchable for mono operation, so if it is not enough power for you, you can purchase another and go monoblock @ 70 watts. For best possible sound from the SM-70 or Pro, used the balanced inputs in monoblock mode if you have balanced output from your pre-amp.

The SM-70 sells for about $350 used and an SM-70 pro usually runs about $400-450 used.

You might find that a single SM-70/Pro is good enough @ $350-$450 and spend the rest on other upgrades or music. BTW, my buddy uses a 1.5 watt/channel "45" based SET tube amp with his original Sonatas. They do run out of steam, but it's a pretty good indication that 10-25 watts should be plenty in most applications. At least for me!

Enjoy,

The Aleph.

The Aleph 3 is a very sweet amplifier.

In a bit more lively amp, you might consider the Clayton S40; there's a used one listed at $1250 right now.

I tend to think the Clayton would be a bit better synergy with the Silverlines (which are already voiced on the warm side), but that's really just speculation.

Best of luck in your quest!

The one and only - FPB 300 Krell,

I have the original Sonatinas and use a Pass Labs Aleph 3 and have not felt the need to upgrade in over 3 years, unbelieveable for me.
