I was reading up on these things and noticed the most common ones seem
to come in two varieties, PQ14/15 and PQ1061/1161. Looks like the
current repackaged ones from Averill are the latter, but doing some
googling I noticed people referring to their PQ14/15's done by him.

Can anybody tell me what the difference in these types is?

I assume it's EQ points, etc. but I couldn't get a sense of the true
difference from the postings I read.

Thanks,
