The overall feel and an upgraded version of PL660 no change in the first edition, at least nothing changes on the performance of the other operational changes did not feel out of the shuttle I set a fixed or SLOW mode. AM and FM sound balance is a lot, I feel l do not upgrade does not matter, is purely psychological acceptance test, and no surprise there.

FM: feeling like an upgraded version of the first edition of the selectivity is not good, such as local 90.5 and 90.7, 90.5 can clearly receive the first edition, while the upgrade version, there are 90.7 channeling sound into; the same two sets of 106.8 and 106.9, the first version of 106.8 to reception, but there are 106.9 upgraded version of channeling sound into. These two stations to the DSP excellent selectivity on its head, G3 better performance on the selective PL660, but one thing I do not like DSP, signal weaker on the stereo off, and the PL660 is still a little noise in hearing under stereo programs.
In addition, both speakers sound or headphone sound, I prefer the I of the G3.

Air Band: PL660 performance better than G3, mainly under the same signal, G3’s volume is too small (low-level gain is small, because the G3 is also a small noise of the back). I have seen through the count, in order to perform well in this band must sound great, even if the noise is accompanied by a great, no problem, this band seems to not pay attention to noise, as if to receive it. Next plan to G3 air band mill about, look at the volume increase.

Long Wave: No comparison.

MW: PL660 performance better than G3, G3’s AM station Anzhe unrepresentative, because from the factory this way, at least worse than 1106.

SW: PL660 and G3 show almost exactly the same, each is difficult to separate the high and low. The only difference is that the degree of speech intelligibility, G3 side alt, PL660 bass side, so the G3 speech intelligibility but slightly better.

PL660’s performance is not as SYNC and SSB G3 ideal, first open the SYNC PL660 significantly after low-frequency noise, whining sound obvious, especially with headphones to listen to (the first edition have this phenomenon, but did not whine so much) . Another SSB voice intelligibility as G3, and adjust the beat frequency of SSB G3 is not as easy.

PL660 speakers in the bass voice of feeling part of the adhesion, the G3 level, so there is no clear, do not know if other users feel the same.
