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.

SEGSEGI have the 6002 and the 565 as well!

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.

What is the bandwidth of this amp?
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.
