Thanks, this is what I keep hearing on another forum, I went out on a limb and ordered this Amp 2.5 weeks ago, hoping it ships soon. I appreciate your reply siI
I just purchased one, have had it for about 10 days now. I had been using an Accuphase E-380 integrated to drive my Spatial Audio M4 Sapphire open baffle speakers (4Ohm, 90db). I am now using the Accuphase E-380 as the preamp and connecting via RCA to the S5.5.
I love my Accuphase but the allure a a pure class A amp was too great not to try. Having listened to the S5.5 and done back to back comparisons withe the Accuphase I will say that the S5.5 does everything better than that Accuphase amp. It has much better control over the bass, and it is faster/tigher. The midrange is where the Accuphase shines in my opinion and I would say the S5.5 is equally as good. The upper range is where the S5.5 really pulls away from the Accuphase, it is much clearer, more detailed and airy. Not a bit of harshness and no listening fatigue.
The S5.5 has added so much detail and clarity to the music it is crazy. Everything is crystal clear and detailed yet the music just flows and sounds amazing, nothing harsh or clinical.
I know for 100% certain the S5.5 is staying in my system. The only question is do I sell the Accuphase and get a dedicated preamp or keep using the E-380 as a preamp only.
Highly recommend the S5.5!
I talked to Doug Dale at Coda about this specifically regarding the amount of pure class A power into my 4 ohm speaker load and he replied that at 4ohm it was up to about 40 watts. Which is still plenty for the 95.4 Db efficient Legacy's. Being that my speakers are bi amped internally for the Bass below 250 Hz through an external crossover the Coda really isn't working too hard.To be clear Coda amps are not "Pure Class A", they are biased designs, I believe they have a Class A mode-not sure how the bias applies but they are biased to A/B after a certain point. There is a difference, most Pure Class A designs are in the 30-50 watt range, while biased designs ("precision biasing" in Codas case) switch over to A/B. Very few Pure Class A designs go up much higher in wattage without being almost unreachable in price.
Isn’t that true of every transistor amplifier? Isn’t this just physics? I suspect that the key selling point of the Coda amplifiers is not their continuous rated output in class A, but the substantial current they can supply from their solidly engineered power supplies when the loudspeaker requires it.To be clear Coda amps are not "Pure Class A", they are biased designs, I believe they have a Class A mode-not sure how the bias applies but they are biased to A/B after a certain point.
