CROWN DC-300 SERIES II & III ? POWER AMPLIFIER- 30 day return policy if this amp does not work according to spec. 150 WPC easily goes to 200 WPC with power hungry 4 ohm speakers like B&W or others running 2 pair in parallel. A little know fact is when driving speakers more than 30 feet away just the resistance in the speaker wires adds a few ohms to the load that will protect this amp even with 3 or 4 pair of 8 ohm speakers being used. It is similar to pushing in an amp protection switch on a speaker switch box, without reducing the sound level by 3DB. Remember this works only if your speaker wires are over 30 ft long going to the other rooms or out into the yard. Budget Replacement for McIntosh mc152. With both units connected to an A/B switch being fed the same CD source going to the same speakers you would have a hard time telling which is which. One thing that you will easily notice is the $ 3000 price difference. Read the many online reviews on this amp even the original DC-300, you will find nothing but positive. Refurbished & Calibrated by a 30yr Tech with lots of crown experience. Normally we replace the large power supply caps but this unit saw very little usage and tested as good as new, so we left them in. We replaced all the electrolytic capacitors and trimmer pots for bias & DC balance. The last of these Series II units made around 1980 had a couple improvements over the earlier Series II, so I put Series III in the title just to get your attention. These later units had improved input circuitry and adjustable transistor bias trim pots, so you could dial it right in right in the middle of the range, so that if slight changes happened over the next few decades, it would most likely still be in tolerance. In addition to that, we also upgraded the power cord as shown. The power Amplifier works perfectly. Unit was bench tested for over a week. It was also marketed as a Laboratory Amplifier due to it high accuracy across the entire frequency range. Its no wonder Hi-Fi, Pro Audio and the Japanese love this amp.
