Crown D60 & D45 Power Amplifiers

I've owned Crown amplifiers and still own a D75 in my main setup. All I have to say is I love Crown amplifiers. I think they are some of the best hidden gems out there. Let's start with some basic specifications. You can easily find a more thorough list online.

Crown D60 Specifications:
Power output: 35 watts per channel into 8Ω (stereo)
Frequency response: 5Hz to 100kHz
Total harmonic distortion: 0.05%
Damping factor: 400
Gain: 26.3 dB
Input sensitivity: 0.75V

Crown D45 Specifications:
Power output: 25 watts per channel into 8Ω (stereo), 95W into 8Ω (mono)
Frequency response: 20Hz to 20kHz
Total harmonic distortion: 0.05%
Damping factor: 400
Gain: 20.6 dB
Input sensitivity: 0.8V
IOC® (Input/Output Comparator) alerts of any distortion that exceeds 0.05% to provide proof of distortion-free performance.
Signal presence indicators verify the presence of amplifier output.

Finding information on the D60 is a bit hard as the unit is older but, for the most part both amplifiers are Class AB. I've read they are pure Class A at very minute wattage. Both can be used as a single unit or bridged. Both are of a dual mono design with individual volume potentiometer. The D45 has some added features such as the IOC, which is nice to have but, it does loses the speaker jacks for a strip. However, both models say their are "Made in the U.S.A.", which means it is 100% made in the USA and extremely well made.

While brand new these units were quite expensive. On the used market they can be had for an inexpensive price and they are worth every penny. These are some of the best sounding amplifiers I've heard. They are very dynamic sounding amplifiers. To put, they are very uncoloured but, packs a lot of punch. "Raw" sounding if you must call it. They remind me of my favourite Hitachi HA-1100 integrated amplifier. Except, these Crown amps have huge damping factor, better woofer control, over the Hitachi.

Professional power amplifiers, with professional build quality for home use? Absolutely! Sure, I had to put some rubber feet on my D75 but, they run my JBL horns beautifully!

I've also used them to run my Bozak MB80 and used them as demonstration amplifiers and they never failed and always impressed. Not to mention, they make excellent headphone amplifiers!
