"There have been significant advances in technology, and the Legacy Audio Powerbloc2 is rated at 325 watts per channel into 8 ohms and 650 into 4, 1.5 Hz to 70 kHz, damping factor of 1,000, S/N of 117 dB, and weight 13 lbs. Compared to the Sony (one of the first Class D amplifiers), the Legacy amp has twice the power, two orders of magnitude less distortion, nearly twice the bandwidth, a 50X better damping factor, and the ability to drive low-impedance speakers."
"At the time I obtained the Powerbloc2 for audition, my reference amplifier was the Audio by Van Alstine (AVA) FET Valve 550HC, a 275 wpc Class A/B design with a hybrid tube/FET input stage driving a MOSFET output stage. Of all the amps I had ever employed in my system, it offered the best sonic performance."
"When I compared the AVA with the Legacy, I preferred the sound of the Legacy, which just seemed to be slightly cleaner in the trebles and slightly tighter in the bass without giving up any of the glorious midrange provided by the AVA. What the Powerbloc2 did for beautiful choral recordings such as The Suspended Harp of Babel by Cyrillus Kreek or Translations by Eriks Esenvalds was simply breathtaking, revealing the nuances of voices in space better than I had ever heard."
"The Powerbloc2 made the music come alive without fail."
"Listening to the Powerbloc2 driving my Focus SEs has been a truly rewarding experience, especially on the large orchestral music that I love by composers such as Mahler, Bruckner, Shostakovich, Vaughan Williams, Sibelius, Elgar, Arnold, Ravel, etc. An especially revealing and rewarding musical experience for me recently was listening to the SACD version of the Mahler Symphony No. 2 (“Resurrection”) with the St. Louis Symphony Orchestra on Telarc. Not only were the big sounds rendered cleanly and powerfully, but the near-silent moments such as when vocalists and/or chorus would enter after a pause were simply sublime."
"What a wonderful amplifier and what a solid value!"
"If you are a classical music lover (especially of large-scale orchestral works, opera, or organ music) with audiophile leanings who is looking for a terrific sounding amplifier with this kind of power and an ability to drive difficult speaker loads, the choices available to you are not many, and if you want an amp that can do so while running relatively cool, taking up little space, and weighing so little while still being solidly built (e.g., premium input and output connectors, a rugged metal case, and a confidence-inspiring on/off switch), I know of no real competition for this amplifier at anywhere near this price."
