I own both the Lamm ML-1 mono's and the Pathos Twin Towers Hybrid integrated. The Pathos is extremely good at a third the cost of the Lamm's. I had a $250.00 capacitor mod done to my pathos and it gives the Lamm a real run....the Lamm is still front and center but the Pathos is the clear winner in terms of value. You can occassionaly find these used on Audiogon for $3250-$3500.
