Mark Levinson 436 Monoblock Amplifiers. $4,500 for both. If you are looking at this you should know what they are. I had these powering Soundlab A-1 speakers. They worked good but I wanted something that would go a little loader so I went with Hafler XL-600 bridged for Mono. I can't say they sound quite as good at lower volumes but they do go louder.
I have the original double boxes and packing that does a very nice job of protecting the amps during shipping. Plus I have additional heavy duty boxes for the original boxes. I think you could roll these down a flight of stairs without damage.
You can come and get them or I can ship but the buyer pays shipping. It won't be cheap because the Amps are heavy and the boxes are big. This is in the Waco TX area. I come to Dallas and Austin regularly and could deliver to that area. 432 528 6953
