Need Nearfield amp recommendation

argonrepublic · 21st July 2011, 11:56 PM

I have three amplifiers available in my budget. I am running 41/2 inch and 61/2 inch drivers on my desktop.
My options are: Hafler TA1600, ART SLA-1 or Harman Kardon HK-770

That's your recommendation? If I double posted, I am sorry. Still need advice.

Oh yeah. I see what you meant. However... I eliminated the AVR254 from my decision. This is a new post requiring an educated and experienced response.

I can do this in 3 clicks ...

-ta-1600 lateral mosfet OP - 60-80W/ch IC front end with small driver stage , all smd construction. laterals are durable and said to have smooth sound.
TransNova Hafler TA-1600;

TA1600 Power Mosfets
-The art-sla
Another IC front end with small drivers and 2 pair small sanken outputs (BJT).

WOW , the HK-770 dual mono PS- 2 pair sankens mt-200 outputs - big power (120++),
full discrete design.
The only issue is that it is older and may need recapping and regreasing. Even if in perfect condition , it is over 20 YO. But , it is by far the only REAL amp of the 3.

The hafler would be the best sounding of the 60-100w units , it uses a newer IC and the Lateral mosfets.

Just a general overview , I have seen and bought dozens of classic amps.

The Hafler is not a IC front end, it is based on the patented Transnova discreet circuit.

I was able to pick up a sealed in plastic HK-770. Would it still need recapping due to it's age? If so, how would I determine which caps are crucial and which brand and type would meet or exceed original capacitors?
Thanks
