Thanks for that. just cannot see those old Elna caps in my Sony power amp living that much longer and remaining with acceptable tolerance. As previously mentioned in the forum under this thread, the QSC amps were suggested as an option. I really do not have all that much mula allotted for home audio. They certainly meet all my requirements. However, I am digging the preamp. I 'm looking for clean, simple, and reliable power source with power to spare so I'm remain lower on the dial. For a short period of time I owned pairs of both the AR-3 and JBL 100s (waffle grills) having the opportunity to A/B them. The ported JBLs were louder given a volume setting compared to the ARs. But the AR3 were much smoother (flat) to my ears with symphonic strings, jazz horns, and vocals. All my friends liked the JBLs better. I easily sold the JBLs for what I paid for them because I had ordered them from a catalogue sales company at a significantly discounted cost.
Yea the Sony TA-3120 seemed to power (stated 50 wpc rms) the AR-3 s just fine for a few decades. But those QSCs would also fit under the preamp much better.
