Gregadd,
Very true. Our c-j preamp (tube) had alot of that rounded quality, on both leading edges and trailing ones. Typical c-j warmth. Pleasant, musical and never offensive, but not fully lifelike. It also lacked adequate power supplies, so our dynamic range wasn't up to snuff.
Our c-j amp was SS, so transient speed was less of an issue. It did have a little waveform edginess, that SS glare, but its single biggest problem was also inadequate power supplies.
