The monoblocks are being utilized in my weekend home. The system is in a relatively large room, about 24 x 28, with a 12.5 ft. ceiling. The speakers are the big line array Dali Megalines, which I’ve owned for seven or eight years. They have to be bi-amped. From the beginning they have been powered by Bel Canto 1000 Mk 1s, and then by the uprgraded Mk II class d amps. For about a year I’ve had the Direct Stream DAC and transport connected into a Class AV processor. Early on in my life with the Megalines I managed to purchase a second Dali crossover and a friend wired the system to provide balanced outputs to the amps. I’ve now completed two weekends of listening to the Monoblocks.
Out of the box, cold, the monoblocks sounded close to what the Bel Cantos sounded. Every night I ran the Purist Audio break in cd during both weekends. Towards the end of the first weekend music began to be more fleshed out in detail, being rather pleasant to listen to, but not at the level for which I had been hoping. Yesterday completed the second weekend (of non-stop playing). Music sounded even more detailed, refined and closer to what I imagine the live presentation would sound like. If I had not heard my main system in NYC, which also has the Direct Stream DAC and transport, I would be a happy camper. This system has a Vitus Integrated, which provides both incredible detail, but also control of the entire spectrum, especially at both extremes. I’ve never heard such controlled bass coming from my B & W 802 Diamonds. The second system, out in the country, using the PS Audio monoblocks is getting closer to what I hear in Manhattan. With only 100 hours on the monoblocks I concluded that they are not yet producing 100% of their capability. I should point out that the breakin for the Direct Stream DAC and the transport, took several hundred hours for the units to come completely into their own and sound their best, as they do now (I am listening as I write this).
