The Diva Blue Sky Amp
Jo Ki has recently been enthusing about the Diva Blue Sky amp designed by musician & designer TS Lim.
divaaudio.com, describes Lim as someone passionate about music, Lim takes special care in the design of his amplifiers to have them convey the full range of musical expression - to make his DIVA equipment "intensely musical".
The Diva Blue Sky a classic design push-pull class AB amplifier, delivering 50 watts of power.
It is specially designed with a high gain - and hence, a high driving capability - to handle some of the notoriously "difficult" loudspeakers such as the LS3/5A, ATC 10 & 20, B&W801, Quad ESL63 and Magneplanars.
Blue Sky Signature, the latest incarnation, features vastly improved mains and output transformers made by the same, Singapore-based transformer specialist who wound the transformers for the excellent-sounding DIVA Tian Zhu.
It also features very high quality European-made capacitors to replace the Cerafine capacitors that were originally used but that has since gone out of production.
Plus, it incorporates DIVA designer's proprietory "ripple remover" circuitry previously used in the Blue Sky Pro. This special circuitry significantly quietens background noise and provides better macro and micro dynamics.
Jo Ki recently posted his impressions of the amp playing the LS3/5A which I quote as follows:
OK Folks, this is the second day I have been listening to Diva Blue Sky driving my Harbeth ebony single wired 11ohm LS3/5A via its 11ohm terminals. The first impression is surprising to say the least! I have not detected any past experiences on switching from 15ohm to 11ohm LS3/5a driven. Firstly, there is no constricted in sound detected in the 11ohm, it is sounding as open and as easy as the 15ohm; secondly, there is no thinning of sound detected from the 11ohm; thirdly, comparatively there is no detection of any lost in detailing, transparency and focusing. Conversely, I detected better focusing and there is a mild improvement in the definition of the sound field. Loudness are identical.For the first time, I think I have found an amp that is perfect for both LS3/5A; irrespective of 15ohm or 11ohm, Diva BS is able to bring both version to a much much closer performance.With the use of BS, I learned that there is no necessity in vintage amp to enjoy listening to the beebs, likewise, there is no necessity in going for old 15ohm LS3/5A also as with the BS, any 11ohm could give you as much musical pleasure as the 15ohm. If sound is what you need, you should give this BS a serious audition.Regards,Jo
