I have heard both the Plinius and the Sim Audio W5 (I have a Sim Audio Moon P5 pre) and I think they are both superior amps and among the best SS you can purchase regardless of price. Regarding tubes, I would only caution to make sure it is truly a balanced design. Just because a tube amp has a balanced connector does not mean it is truly a balanced amp. I assume when you say basement, the cable length is going to be quite long. I also like to see my tube amp in case a tube arcs. This is rare but it does happen. I would suggest (if you can) an audition of the Plinius and the Sim gear, as I stated earlier both are good, but ultimately (and especially when talking a kilobuck purchase) your own ears must be the judge. Best regards, Mike
