LAB REPORT: QUAD ELITE QSP

摘要

In answer to the question on the lips of every audiophile 'how does the QSP compare to the 909?', I'm bound to say 'very closely indeed'. In performance terms, the two are very similar, with the QSP behaving like a slightly polished 909 albeit offering an identical +33.1 dB overall gain. I compared the QC Suite reports for both [the 909 measured in Oct '07] with the following observations - power output 155W/260W versus 155W/255W (8/4ohm, 909 vs. QSP) and dynamic power output 155W/85W versus 195W/110W (2/1 ohm) indicating that the QSP is just slightly more load tolerant if no more powerful in practice [see Graph 1, below].
