Product Description

Starting in the 1980s, Adcom has made a name for itself with high-quality receiver and amplifier components that punch well above their price—and the GFA-6002 is no exception. A powerful amp and a great value, it can drive most two-channel setups and offers plenty of reserve power when working with demanding passive speaker setups Read More

Has anybody compared this amp to the old GFA-535 series? What is the purpose of having R/L channel outputs? Thanks.

I own this amp. It does sound awesome. I pair the GFA-6002 with an Adcom GFP-565 and I am very happy. For those without a GFP-565, I have paired the GFA-6002 with a Little Bear P5 (with audio grade tubes installed) and it sounds fantastic. I also have an older generation Adcom GFA-545; the GFA-6002 sounds better.

70 watts is a little weak. Something over 200 watts is preferred.

True. That is why it is my personal opinion.

Also depends on speaker efficiency. For example, running a 86 db/w set of speakers using a 1.5 watt SE OTL amp will sound quite different than running it a pair of La Scalas with 105 db/w sensitivity. But again that is my personal opinion. The less efficient the speakers, the more power the better the sound. That is from my personal experience.

bsatowWell most amps worth a damn are within 1db 20Hz to 20kHz but maybe these specs from avhifi will answer your question: Power Rating (To IEC-CEA-490A Requirements) 70 Watts continuous average power into 8 ohms at any frequency between 20Hz and 20kHz with all channels driven at less than 1.0% THD. 100 Watts continuous average power into 4 ohms at any frequency between 20Hz and 20kHz with all channels driven at less than 1.0% THD. Bridged Power: 175 Watts continuous average power (one channel) into 8 ohms at any frequency between 20Hz and 20kHz with at less than 1.0% THD. IM Distortion (SMPTE) 1 watt to 70 watts into 8 ohms 0.05%. IM Distortion (CCIF, Any Combination from 4kHz to 20kHz) 70 watts into 8 ohms 0.01%. Frequency Response at 1 Watt into 8 Ohms 10Hz to 20kHz +0, -0.25dB. Power Bandwidth (-3d B) 5Hz to 130kHz Dynamic Headroom Into 4 Ohms 1.8 dB. Signal to Noise Ratio, A-Weighted 70 watts into 8 ohms 100dB. Gain 29dB.

The pdf manual for this amp leads me to believe this is a class A amp, but I'm not certain. If it's class A, make sure it gets plenty of ventilation.

fdawg4lI significantly doubt this is class A, true class A amps are very expensive and typically yield a much lower wattage than their A/B counterparts at any given price class. Oh and most class A amps advertise that about 4 words into their product description. : ) This is Adcom's cheapest stereo amp

I just bought a used Adcom 7050. Two comments: (1) various models are widely available used at good prices, (2) if the sound of my amp is any indication, this amp will sound awesome.
