I feel sad about this thread for the following
1. I don't mind hearing people saying ferrites work. I've followed the Blu 2 and DAVE thread long enough and know that ferrites works in the case of Blu2-DAVE combo. Whether it works with HMS-DAVE remains to see.
2. This is an impression thread so people say that ferrites work with HMS-DAVE or not work with HMS-DAVE are both perfectly acceptable.
3. Given that seller of a particular cable is willing to give an enough long time for the potential buyer for a free trial (probably with deposit), I see that a fair deal. I have no skin in any BNC cable and is just a user like most of the headfiers here.
4. There are lots of post here that stated close-minded opinions or illogical conclusions.
For example, some say that Rob is a good enough engineer so that he would be able to take care the RF business. SO THAT the RF business of the HMS should be handled completely. The conclusion "SO THAT ..." is flawed. Rob is one of the best engineer that I can think of in his field and he know the impact of RF long before the birth of the Blu2. However, Blu2 is susceptible to RF, a well known fact and hands down. If the SO THAT conclusion was true, then Blu2 should not be susceptible to RF. This shows why the conclusion was illogical.
Another example was something like the HMS was so expensive that if it's susceptible to RF, then it's a crap. Please look at the real situation, the stock cable was pretty good and people wants the best. To get the last 5% or 1% would be very expensive. Just look at the pricing of the Intel CPUs vs their clock speeds.
5. Listening is always subjective but if many trusted people honestly report the same thing many times, the experience become objective. Please check how Faraday discover the Faraday's law. Many thought that the theories were already complete and took the observation just random errors. There are many things that we don't know in audio science. So explore if possible is the way to go, waiting the "consensus" of the listening impression is another.
6. Be humble and curious so that we may learn more and falsify more. Rob always show this attitude.
7. The golden phrase that I've learnt from HeadFi "If it sounds good an measures good, great. If it sounds good and measures bad, you've measured the wrong thing" It still holds in most of the cases.
I came here to see if people find optical equal to or better than USB as the input for the HMS. The reason is then I may save money. YMMV
I would rather like to read more real impressions/experiences here.
My 2 cents.
