Yes Gryphon probably even better again into low impedances, they are also complimentary bi-polar amplifiers
EG: the Antillion monoblock can give 7500w peak into 0.25ohm

George, I don’t know Antillion amps and I’m sure they are great, but 7500W into 0.25ohms requires 173 amperes? What kind of power supply can deliver 173 amperes? What about size of conductors? Most of the current will go to woofers, but there is a choke there that has on average 0.1ohm. Power dissipated at this choke would be close to 3000 watts. This choke would evaporate. Perhaps we are talking about average power ( sinewave typical for bass frequencies). This average power would be half of peak power equal to 3750W. It will result in 122 amperes and woofer choke will get close to 1500 watts and will still evaporate instantly. What am I missing? |
The Sugden A21se single ended pure class A will give your pass lab a run for its money. It is based on the original circuitry developed by Sugden well over 50 years ago. They pioneered SS class A, they were first....and this model is only the lower tier model....the Masterclass series is even better...go and read all the countless wonderful reviews for the A21se. "The A21 was the worlds’ first production pure class A transistor amplifier and a great success. The partnership with Richard Allan was short lived and within a year the amplifier was renamed the SUGDEN A21." https://www.sugdenaudio.com/a21-history https://www.sugdenaudio.com/james-sugden |
Change the premise of the comparison; I’d wager the D’Agostino amps would be used typically in conjunction with larger, über-expensive, multi-way, lower efficiently and passively driven speakers with rather complex and power-draining cross-overs, which are in the dire need of a proper amp-kick in the b*llocks to begin with to have them wake up. Use an amp costing much less or even a fraction of the D’Agostino in an active configuration with higher efficiency speakers, and that cheaper amp would be comparable looking into a much easier load without the interference of a load-varying passive cross-over. Amps like the D’Agostino’s are a symptom of extravaganza and difficult speaker loads; change the circumstances, and it’d render them unnecessary. |
