Older, high current, very stable into low impedances, and sounds like the real thing (fast and highly controlled Bass reproduction/excellent square-wave response), describes the first (and subsequent) Hafler TransNova amps. ie: (https://www.hafler.com/pdf/history-of-the-transnova.pdf) Early model test results: (https://www.stereophile.com/content/hafler-transnova-9500-power-amplifier-measurements) Not too salty, either: (https://reverb.com/item/2032061-hafler-9505-trans-nova-power-amp-black) or (depending on your wattage requirement): https://www.hifishark.com/search?q=hafler+9303
Ideas for amp to run woofers on a bi-amp system.
I own a pair of speakers that dip a bit in terms of impedance and I want experiment with using a solid state amp to run my woofers in a bi-amp configuration. We do not carry a solid state electronics line currently. Speakers have 3 pairs of posts. I will be using the Zesto Bia amp to run the midrange and tweeters and need suggestions on a good amp/amps to run my woofers. Perhaps Class D? Any ideas on older high current amps that can be had used? Thank in advance!
