Here we have a wonderful Modification service for these sleeper preamps to turn them in to a Grace 101 times two only with a warmer richer tone.
On these preamps we do a Nice input stage modification using Burr Brown high performance opamps, some de-coupling and coupling techniques as well as some other trade secrets to really put the performance in these preamps.
Interstage coupling modifications are performed as well as output stage mods for optimum performance as well.
Finally the power supply is also modified for the lowest possible noise and higher current delivery to accommodate the the new modifications.
The result is a very warm large sounding preamp that is focused with a lot more headroom, bandwidth and musicality.
The noise floor is also lowered and the audio image is clear and extremely musical.
