SimAudio Celeste 4150SE Power Amplifier, NAD 1155 preamps with Burson V6 Opamp

Excellent experience, and surprised how well Burson V6 took to older higher voltage equipment. V6 Classic used in SimAudio 4150SE Power Amplifier (2x Single). Also used in two older NAD 1155 preamps (2x Dual, one in each preamp). Widened the stage, improved lower frequency response, and more present sound profile.
