Review on Coda Technologies 16 Amplifier went live today

Yes. FET = field effect transistor.

I think the approach makes a lot of sense, especially if the 15.5 has the new input stage. Last I checked there was a used 15.5 with the new input stage on Audiogon listed for $6,600. No brainer over the No. 8. 

Differences off the top of my head (15.5 vs. No. 8):

• Class A bias: 100W vs. max of 18W
• Power supply filter capacitance: 200,000 microfarads vs. 80,000 microfarads
• Output transistors: 28 per channel vs. 20 per channel
• Weight (due to larger case and massive heatsinks): 110 pounds vs. 62 pounds

There could be others as well, but this is just going off of spec sheets. Seems the bigger amps have better SNR measurements as well and better tonality. 

The SNR of the #8 is 116 and the #16 is 130.

I have heard from other No. 8 users that this amp rarely leaves its Class A rating and if that’s the case, wondering if adding more filter capacitance to the No. 8 would bring it closer to the sound of the No. 16 without the added weight : )

Yup, almost like a Coda 12 that has more capacitance and maybe 40-50 watts class A for a price between a 16 and 8.

I wonder though if the speaker is barely leaving class A, would we really get much benefit from the 16 over the 8 ?
