(Originally written by Rouxxx/translated from Audiofanzine FR) No installation problems. SUITABILITY/PERFORMANCE Very low resource consumption with a Core 2 Duo E4600 and 2 GB Ram. OVERALL OPINION The 1973 is very interesting for its high-frequency band. It's worth to buy the plug-in just for this reason regardless of the other possibilities. It allows you to brighten the sound without making it aggressive. The low-frequency band can also be interesting. But I found some weak points: - The mid-frequency band is virtually unusable because of its too narrow Q factor which produces unpleasant resonances pretty fast. - It's impossible to accurately adjust the low cut since it only has fixed values. This product would be worth a 10 considering its magic high shelving filter, but I only give it a 7 because of the useless mid range and the inflexible low cut.
