I moved from an Era Gold V to a Revelation M around teh turn of the year (which I believe is very similar to the Reflex M). Drewan's comments mirrored my findings; in relative terms the Era Gold appeared quite narrow by comparison in sound stage, the Revelation being more natural in all aspects and the Bass being firmer, better defined and again more natural - the Revelation possibly a little lighter in overall balance; likely due to better definition and less colouration. Not huge differences but certainly worthwhile and as said by others you could live with either quite easily.
As stated elsewhere on the forum I upgraded my mains to PSU cable around the same time. Upgrading the mains leads with the Era Gold I found prefereable to the Revelation with stock cable in pretty much all aspects, certainly far more natural. Rev + cable far better (IMO). Can't go wrong with either the Era Gold, Reflex M or Revelation, ideally with PSU (and with upgraded mains throughout but that is another debate). Good luck. Richard

Couple of questions: Were the AD opamps installed in the Era Gold Reflex? What exactly were the "tweaks" Graham mentions for the Era Gold Reflex? Thanks for any information.

The AD opamps were installed in the Era Gold Reflex and one of the tweaks was to use them in parallel which helped reduce noise by roughly 3dB. The opamps were a pain to use because they suffer from flicker noise, and in their intended use of video such flicker noise might not be an issue because of the bandwidth (range of frequencies) covered. There were other tweaks which were alterations to component values intended to make a more natural sound. Eventually though I realised that the gain profile of a record/MM cartridge EQ was better matched to other specific opamps, such that it 'held' the loop gain more constant over the entire audible range (and beyond to closure). This eventually resulted in the patent application for the "NPS" and the introduction of the Accession. At that point in time the Reflex M as we now know it replaced the Era Gold Reflex, and later on it was found that adopting a different opamp in the Era Gold, suitably 'breathed upon', produced an exact match gain-profile to the original opamps and the resultant sound was indistinguishable from the original design. Also during the use of the AD opamps I was able to use Elna Starget capacitors but RoHS in 2006 outlawed them from commercial production, and so the last units using the ADs used Nichicon Fine Gold's and/or Panasonic Audio capacitors. Further research concluded that these were responsible for an etched sound in the new designs, which I don't think were released until an alternative solution was found. The rest are trade secrets. |
