Know before you buy
The Class A configuration ensures the amplifier operates with exceptional linearity and minimal distortion, resulting in a highly natural and lifelike sound. While it runs warmer than Class AB amplifiers, this design choice is fundamental to the E-700's ability to capture the nuance and emotion of a live performance.
Yes, the E-700 is engineered to handle demanding loads with ease. With a high damping factor of 1,000 and a four-fold parallel push-pull MOS-FET configuration, it maintains excellent control over speaker drivers, even when impedance drops as low as 2 ohms.
Balanced AAVA eliminates the traditional variable resistor, preventing signal degradation and impedance changes at different volume levels. The addition of ANCC technology further reduces noise, ensuring that the signal remains pristine and highly detailed regardless of your listening volume.
Absolutely. The headphone section is designed to a standard that rivals dedicated, standalone headphone amplifiers. It provides the same level of clarity and phase coherence as the main speaker output, making it an excellent choice for critical listening sessions.
A damping factor of 1,000 indicates the amplifier's superior ability to control the movement of your speaker cones. This results in tighter, more accurate bass response and improved transient detail, preventing the 'muddy' sound that can occur when an amplifier fails to stop a speaker driver precisely.
While the E-700 is designed to excel with balanced XLR connections, which help reject external noise, it remains a versatile centerpiece for your system. Using balanced inputs will provide the most benefit in terms of signal integrity and noise floor reduction.
