I used to own the D'Agostino Momentum M400 monoblock amps (2 pairs) driving the Wilson Audio Alexx speakers with the Audio Research Reference 10 linestage preamp and DCS Vivaldi full four stacks served as my digital front end source components. They sounded fabolous together. Recently Dan released a new series called the Relentless monoblock power amps which carries a price tag of $250k/pair.
Early this year I went through major upgrades with my dedicated reference 2ch setup. I traded in the D'Agostino Momentum M400 monoblock amps and the ARC Ref 10 linestage preamp for the Naim Statement gears, which consist of the Naim NAC S1 linestage analog preamp and the Naim NAP S1 monoblock amps. I also traded in the Wilson Alexx for the Magico M6 speakers. But I still have the DCS Vivaldi full four stacks, which consist of Vivaldi master clock, Vivaldi upsampler, Vivaldi DAC, Vivaldi CD/SACD transport.
The Naim Statement gears are cost-no-object design preamp & monoblock amps and are significant step up sonically and performance wise from the D'Agostino Momentum M400 monoblock amps / ARC Ref 10 linestage preamp combo but the price increase is significant too. I highly recommend the Naim Statement gears which consist of the Naim NAC S1 linestage preamp & Naim NAP S1 monoblock amps if you can swing them. They are expensive $270k for both the preamp and the monoblock amps. $90k for the NAC S1 linestage preamp and $180k for the NAP S1 for the monoblock amps.
But I'm still using the ARC Ref 10 phonostage preamp for my turntable. I have a Kronos Pro turntable with a 12" Black Beauty tonearm, Air Tight PC-1 Supreme mc cartridge & a discrete linear class A power supply unit for the turntable.
