H/K has a lot of fans and the receiver is probably the best component of the system.
The Technics turntable? The only real criticism of the SL-QD3 is that it's a p-mount tonearm, which limits your choice of cartridges. Otherwise, it looks like it has very nice wow/flutter and rumble specs, only surpassed by the expensive and massive SL-M1, M2 and MA-1. (information from the
Vintage Technics Database).
Akai speakers are probably the weakest link in the chain. Akai was known for tape recorders, then receivers/amps. Speakers were a sideline. It's still a reputable brand, though. But since speakers are so much a matter of individual taste, what counts most is that you like them. I have a pair of Pioneer CS-103 speakers that are "statement" speakers - the statement they make is "
cheap!!" - but I like the sound of the things, possibly because some unsung genius at Pioneer actually achieved reasonably well balanced frequency response with dirt cheap drivers, and some kind of half-assed crossover.
I'd be leery of speaker power ratings; I tend to simply follow the rule of thumb of not turning the volume control past the 1 o'clock position for phono input, 10-11 o'clock for other line level inputs, such as CD's.
