I would investigate the availability of replacement mechs as I seem to recall they are no longer trading and spares are not easy to obtain.
Nothing remotely special. Modded Nu Vista on Wigwam for way less money and blows it into the weeds.
To be honest, I've heard nothing at any price anywhere that 'blows [the Opus 21] into the weeds' - that's typical audiophile hyperbole - but equally there are better players and DACs around these days. The MDAC - modded or not - and any competent CD player as a transport will give better results for less money. I've owned both, and heard many more.
