The ups and downs of tube vs. SS...

Tubes are just like Ferrari, Porsche, Rolex -- toys designed to entertain
Solid states more like Toyota, Honda, Swiss Aarmy --  instruments designed to deliver.

For a near field desktop system and to get into tubes, check out the miniwatt 6AD10 single ended amp.  It's 3.5 wpc, single ended, and won't set you back much.  You'd be surprised just how loud 1 watt can get with the right speakers and they are saying the 6AD10 is superior to a 6BQ5.

The Sophia Baby is also a nice sounding 6BQ5/EL84 amp.  I believe it's about 10 wpc push pull.  The EL84 is one of my favorite tubes, it's very neutral and sweet sounding and has excellent bass.

It all depends on your budget and speakers too.  

Tubes, at their best, do sound better but the cost is not insignificant .
If you want REALLY good tubes the cost can easily be twice the original
cost of the amp over its lifetime .

Here ya go!
