GIven that the Triton 3 is a scaled-down Triton 2, read the Stereophile review of the Triton 2, where reviewer Deutsch auditions the speakers with a SImaudio SS amp and two much lower-powered tube amps. Although the SS amp produced tighter bass, even with the Triton's built-in bass amps, the tube amps had more harmonic richness and tonal authenticity. In spite of its low price, the Tritons have the resolution to reward more harmonically rich amplification.
Also, according to the TAS review of the Triton 2's, Sandy Gross himself powers his with a low-powered SET amp:
According to the reviews I've read, the Triton 3s are probably one of the *best* candidates at that price range to get full-range sound out of your EAR 859.
Also, according to the TAS review of the Triton 2's, Sandy Gross himself powers his with a low-powered SET amp:
Sandy Gross, for example, drives his personal pair of Triton Twos with a relatively small, low-output SET amplifier, which is the sort of option you cant realistically hope to pursue with such affordable high-end speakers as the excellent but decidedly power-hungry Magneplanar MG1.7s. In practical terms, this means the Triton Twos are not only fine value-priced speakers in their own right, but also make suitable platforms upon which to base excellent value-priced systems (this in contrast to well-priced speakers that require a gazillion dollars worth of amplification in order to sound their best).
