I have gone early to bi-wiring, went back to single wiring briefly and was puzzled by the loss of quality (less clear, and various levels of sibilance. It sounds so so much better in term of high-low frequency balance, transient attack with clean smooth bass & silky soothing highs. Also replaced ALL cheapie skinny wires inside with AWG#12 thick cables. I replaced its lousy micky-mouse like factory-built X-over board with my customer design/built BI-WIRING X-over board with high-power polypropylene caps & wire-wound resistors. Knowing the technical merit of BI-WIRING, I converted it to bi-wiring many years back. Have you given a FAIR audition to this Lumina III which provides bi-wiring connection at the back ? It is there for one single reason: to improve the sound as it costs the loudspeaker maker more to design/build a bi-wireable X-over network !!!įYI, my KEF 2-way standspeakers got only standard 2-terminal connection like most most brandname loudspeakers, irrespective of pricing. I don't recommend this speaker for use with source components that are themselves too forward in the treble," quoted J.A. Hopefully you could enlighten me on this with your profound live recording experience. My question is: why this BBC Prom performance in the Royal Albert Hall, London sounded so lousy as said above. This short music piece is what I use to test the transient response of a HIFi system. The performance started with some low low crawling organ bass notes followed immediately with sharp & powerful kettle drum beats. I got 5 LP of the same title, only this LP really satisfied my very picky ears. It was performed by Boston Symphony Orchestra, conducted by William Steinberg in 1971. The best kettle drumming effect of this music piece so far I auditioned, is delivered by my DGG Resonance label LP (2535 209): clean, sharp, punchy & powerful. The kettle drums beating immediately after the first starting low low organ bass notes, sounded soft & blurred ! Same music performances on YouTube, like one conducted by Zubin Mehta in another concert hall in June 11, 2014, delivered sharp & punchy kettle drums beat. The issue just came across me when I listened to BBC Prom in the Royal Albert Hall performing Richard Strauss Also sprach Zarathustra around 15 years ago streaming on YouTube this afternoon (my day off).
