Transients come from nowhere, without warning. Cymbals are clean and without edginess. The amplifier did run into a little bit of trouble at the extremely dynamic end of the spectrum. This wasn't so much evidenced on cymbal work but a little further down the frequency spectrum, say on the trumpet on the Isle of the Dead . When pressed, the trumpets sounded little thinner than they should.
Studio recordings sound more studio-like and hall recordings have their characteristic ambience.
The piano sounds far more realistically sized. Scott LaFaro's double bass exudes a sense of internal volume and fullness. Ray Brown's bass sounds more ill defined, verging on a one note bass sound, than does LaFaro's bass. You feel like you can walk up to the instrument and grab them away from the musicians. Instruments are clearly localized and the air or ambience around each instrument is clearly separated from the neighboring instrument.
