In Reply to: Sony STRDE935 straight trade for Yanaha RX-V1070..?????? posted by Joel on March 29, 2000 at 06:08:54:
Hi Joel,Are you currently dissatisfied with the Sony's performance, or do you just want to dump it because a lot of people bash Sony's DE line? You would be taking a step backwards in terms of features as the Yammie only has DPL. If you have a DVD player or plan to get one soon, I would not make the trade. If you're not satisfied with the Sony, sell it for what you can and get a receiver you will be satisfied, be it Yamaha or otherwise.
Regards,

Nothin wrong with the Sony it's excellent for movies and loaded with tons of features, I would like better 2ch performance and the Yammie has lower THD in 2ch modeBTW I do have a Sony DVD optically connected to the Sony
You wouldn't make the trade.?
THD has nothing to do with sound quality. It's simply a measure of when the amp starts to distort. For example, a receiver could be rated 100w X 5, 0.8% THD 1kHz. Or it could be rated 70w X 5, 0.05 THD 20-20,000Hz. The second rating is much more useful as it is across the entire audio spectrum, not just at 1kHz, and the THD is lower. The first rating is more like a "cheat," but there aren't any rigorous standards with which manufacturers have to adhere to. That's changing somewhat.Anyway, your Sony receiver could be rated 100w X 5 at 0.8% THD, and have a corresponding 0.05%THD at something like 65w. Now, if the Yamaha was rated 100w X 5 at 0.05%THD, then obviously it can play louder, but that says nothing about the sound quality.
If your speakers are 91dB sensitive, then you're only using 1 watt to get 91 dB. For each 3dB louder, double the power. Even at 103dB, you're still only using 16 watts. So, THD figures don't enter into it. However, it is true that in general Yamaha has better amps in their receivers than Sony DE line, unless you can hear a difference with your speakers in your room, there's no reason to make the trade.
Further, since you have a Sony DVD, can't you use S-link to make things easier? In short, don't make the trade. If you want better two-channel performance, get an outboard amp or an integrated amp and run a totally separate music system. You'll be much happier in the long run.
Hope this helps,
RichardH
Thanks for the help I'm not going to make the trade BTW I am using the s-link
