The mid 80's 7xxx series was essentially just an update of the second generation ss amps(2125, 2205, 2255, etc.). At that time, simply having ample dynamic headroom was considered to qualify an amp as "digital ready", which was the only intention of the moniker. Now, such a label is something of a negative, in these days of analog revival & SET amps, and all that. The 7xxx series & the previous 2nd generation amps, in my opinion(I was selling both series when they were current) had very little to complain about in terms of tonal balance, transient response & other technical parameters. However, they were simply not very musically involving. The first generation ss Macs(2505, 2105, 2300, etc.) were far more musical, and are still among my favorite ss amps overall. I don't think Mac got back to this kind of quality until they brought out the MC1000 & MC500 amps. These, of course, were far more money than even a mint condition, new-in-box old MC2300 would fetch on ebay, and for the price difference, I'll take the old amps.
