Joe Casey the Dagastino Mommentium is in our opinion a good sounding product but way over in flated for the sound quality it delivers.
When we were shopping for a reference electronics line we considered Dag gear but when we looked at the prices were turned off, it does appear you are paying alot for that look and the craftsmenship.
Compare a Dag s250 which costs $35k for a 250 watt stereo ampfor the same money you can get a T+A P3000HV a 300 watt stereo amplifier with a 1,000kv transfomer and their upgraded power supply which add a 1.2kv transfomer which powers the output stage and the internal transformer powers the input stage of the amplifier so you have a two chassis reference amplifier for $3k less with more power and a suprior topology and if you want to start you can just purchase the P3000 HV amplifier for $19k this is a 300 watt stereo amplifier which can also be bridged into a 480 watt monoblock.
So even without the upgraded power supply you are $19k for a very musical very powerful stereo amp made with extraordinary parts quality, design and technoloy vs $35k for the Dag.
Compare the Mommentum integrated at $45k to the T+A P3100HV a $23k T+A unit, the T+A gives you an option for a built in phono card, room eq functions and 300 watts of power also with an option to add the outboard power supply, and you are still paying $22k less!
