The output stage of the Boulder is a CFP with a voltage gain of about 5. 25 years down the road, today's opamps are better than ever. Considering how long it will take to make a pair of JE-990 from scratch, I would build the amp with a nice modern IC. That way you could listen to it while getting the other stuff together. Be interesting to compare the two after you're done. |
