There's nothing like a well designed class A amplifier to bring out the best performance in your speakers. I once owned an original Bedini 25/25 that was a nice match with my 15 ohm Rogers LS3/5A's. It was also supposed be a great match for the original QUAD ELS 57. The Bedini 10/10 was also a good choice for the ELS 57. One of the best sounding and most powerful class A amplifiers that I have ever heard is the Classe Audio DR3VHC. It was one of Classe Audio's first products when David Reich was running the company.
Watts! How many do we need?
Got a new amp. Accuphase P-4600. It’s great. I love it.
150 watts into 8 ohms, 300 watts into 4 ohms and it has meters so I can see wattage. Have them set on freeze so I can see the highest wattage during the session.
My Harbeth speakers are not very efficient. Around 86db. Their impedance is an even 6 ohms dipping no lower than 5.8 ohms.
Playing HiRes dynamic classical recordings ( Tchaikovsky , Mahler) at room filling volumes I have yet to exceed 1watt..
Amps today offer a lot of watts some going to 600 even 1200 watts. Even if you have inefficient speakers with an impedance that dips down to 2 ohms do we need all this wattage or should we be focusing on current instead?
