Music is the only language in which you cannot say a mean or sarcastic thing.

Finally!  The annual International Sight and Sound Exhibition is here.  Its an annual event that I always look forward to, as it is the only hi-fi related show that is available in sunny, tiny Singapore.  Its my get-away from the usual chore of work to immerse myself into something that I really enjoy, i.e. listening to music and lusting after the latest wonderfully built (not to mention wonderful sounding) hi-fidelity components, be it speakers or cd transports or ...  you get the picture.

One of my goals when I attend the event is to see just what worthwhile thing I can buy for under $200 to try out in my system.  The year before, I bought the Solid Tech Iso-Clear isolation feet at the show discounted price.  I am still very happy with it as it does work well under my CD transport, taking over the duty of my set of Golden Sound DH “Super” Cones.  So, this year, it is no exception.

So, as the title gave away, I eventually bought a pair of supertweeters from Leo Research for S$80/pair (show price).  I have to admit though that I was rather skeptical at first, and I actually left the show without getting anything except CDs.  At the Leo research room, I did notice the supertweeters perched on top of a pair of bookshelf speakers.  I asked about them and promptly was treated to an A-B comparison of just what the supertweeters do for the overall sound of the system.  Even though the show condition did not allow for a proper audition, I did manage to discern the difference with and without the supertweeters in place.  On the whole, with the supertweeters in place, the system seemed to exhibit more information from the music.  But, like I mentioned above, the cramped and crowded room did not allow for a proper audition.  I went away intrigued but unimpressed. 

When I got home, I decided to check out my Grand Piano Domus specifications, specifically on its highs.  It topped off at 20kHz.  Hmm...  I had really thought that it goes higher than that.  Anyway, I then did a search on the WWW about supertweeters in general, and lo behold I am very surprised by the many versions and price range that are available in the world market.  The cheapest I found (outside of Singapore) is AV123's Onix ERT at US$349 (excluding shipping) while the most expensive is muRata's that cost close to US$3000!  Well, I certainly will not buy the muRata but the AV123's Onix ERT looks interesting and more affordable.  However, it cannot beat what Leo Research is offering (in terms of pricing) for their supertweeters at the ISSE.

So, a quick call to my audio buddies (to find out who have yet to attend the show) to ask one of them to buy the supertweeters for me.  I managed to find my man and, on the very next day, the supertweeters appeared in my place.  I wasted no time installing them onto my Grand  Pianos.  Of course, I played my system BEFORE I inserted the supertweeters, so as to be sure how they actually impact the sound.  I had however forgotten that I can do an A-B comparison easily because the supertweeters can be disconnected / isolated from the Grand Piano quite easily via its single RCA connection behind each supertweeters.



In the solace of my home and my system, with the supertweeters in place, there are definitely greater clarity achieved but without any discernible hardness or sharpness in the highs.  The bass was also tightened and bass lines are easier to follow.  I thought perhaps I had let the fact that I installed the supertweeters lulled me into imagining these improvement.  So, I asked my wife to check them out, and did a double-blind test on her and sought her opinion each time I allegedly connected/disconnected the supertweeters.  She was able to get 100% right each time.  Her observations matched mine too, with greater overall clarity being the most obvious difference.  She also noted that there is no sharpness (her own words) in the sound, just clearer, like the singer and band are physically in the room. Without the supertweeters, my system sound had suddenly become veiled.  Its amazing what you don't know, isn't it?  You would think that I am happy with what the supertweeters wrought, right?  Well, in a way, I am very pleased with the purchase and result.  But, I am intrigued by the thought on improving the supplied interconnect cable, which was made with the ubiquitous red and black wires and the loose fitting (spell: cheap) RCA connector.  I mean surely changing out the interconnects with a better set (read: better wires and connectors) should improve the overall quality and output of the supertweeters, right?  That is the basic premise all audiophiles will attest and agree to.



So, in my next visit to X-Audio, I bought a pair of 1.5m QED Qontour Ultra-Flat 99.999% OFC speaker cables and a pair of good grade RCA connectors.  After fabricating the QED interconnects, I listened once again to the system with the red/black interconnects before swapping them with the QED version.  I think you know the answer to the outcome.  The QED interconnects were able to allow the supertweeters to give greater output (I hooked up 1 QED and 1 red/black per side for direct comparison).  Yes, I can hear the output from the supertweeters.  So can my children.  With both QED versions installed, the overall sound quality is really addictive, and I really enjoy the improvement the QEDed supertweeters brought to the sound. 



So, all in all, I really am glad that I decided to purchase the supertweeters and upgraded the supplied interconnects.  I did not realise what I have been missing until now.  The supertweeters not only improved on the overall clarity of the music, it also tightened the low bass region, transforming the bass into easily discernible lines to follow and enjoy.  The only catch now is....  what about the other supertweeters that are available out there.  The Leo Research supertweeters are titanium based dome units.  There are ribbon-based ones out there as well, and we know what ribbons can do to the highs.  Alas, I suppose someone else will have to try it because frankly, I am very happy with what I got considering what I have paid.  Until the next ISSE...

anyway, there is a leo research showroom in adelphi 4th floor. you can order and pick up from there too. thats what i did.
