Well, can't argue with them for being honest!
To be fair, this is what I have found so far. The quality of the compounder and the quality of the RF transmission is absolute key. As I have stated before, I'd love to try the LD systems to give an idea of what the quality of those are like in comparison to my benchmark of the PSM900 and EW300.
The other thing is, it depends what you are used to. If you have never used anything else, then pretty much any in ears system is likely to be a revelation. Similarly, I guess it depends what your expectation from an inears system is. For example, if I hear of somebody saying the PSM200 is great, then I immediately question what that user is staying. Having tried that system extensively, I can say, it's pants and I would not be happy using it. Crappy RF, sound quality is really harsh in the top end and the bottom end is ugh. The compounder is not good.
If you are hellbent on inears, my advice - and I think this has been echoed in the thread throughout, is just buy right from the word go. It will save you money in the long run. Save up for the Sennheiser EW300s G3 and you are away. I may change that statement to include the LD system when I eventually get around to hearing it but obviously at this stage, I can't comment.
