Measurements Creek 4040A
The Creek measures up nicely. We see decent results that belong in this price range. The noise floor is around -110dB with a rising noise floor towards 90 kHz. Creek has it under control, but it could be a little lower at the end we think.
The response and phase suits a class D amplifier. We can clearly see the effect of the filter. The response slopes down a bit towards 20 kHz and the phase turns up there too. We see this with all class D amplifiers.
Power output is approximately what Creek says it is. It’s just depends where you put the measurement point, we now know. Looking at 8 Ohms, we see that the Creek reaches almost 60 Watts at 1% THD. At 4 Ohms it doesn’t. Then we just hit 100 watts, not 110…
Power supply noise
Noise at the grid is pretty well under control. Common mode is around -80dB and differential mode -84. Could it be lower? Of course… but in this price range it’s just neat.
I bought the Creek 4040a based on this review and havnt been disappointed. I don’t understand why it hasn’t had more attention? At first I tried to pair with Dali Opticon 1 mk II but I don’t think it was powerful enough for these speakers ( I had to have the volume well over half way for decent sound). Also, the Opticons were a tad too bright for me. I now have the Creek paired with Elac Debut 3.0 db63 which is much better. There doesn’t, however, seem much choice under £1000 regarding a warm ish sounding speaker. 🤔. Keep up the good work Alpha team!
Hello Simon,
Nice to hear you like our work. What a great combo you have there. I love the Elacs as well.
Best regards
Geoff
