Does Yiur pre amp have gain switch’s for inputs. most do some dip sws some menu driven. don’t knock op chip inputs unless you hear itIn the Baltic 3 manual, I came across the following section that explains the gain problem. I understand the hi-low gain settings as the workaround, but I gather that Lukasz is more generally recommending a passive preamp volume control in place of a chipset--is that correct? Also note the second paragraph on opamps. I know my Pass Labs Int-60 has a chip volume control, but I'm wondering if I also have a case of the dreaded opamps? Does anyone know if the newer Pass preamps have a different volume control design?
"Generally - we prefer the sound of the DAC with high output levels, and most amps don’t have any problem with that. A simple potentiometer or stepped attenuator takes care of that. Only solid state chip based preamps will saturate and distort thats why we need to know in advance about such solid state chip volume system being driven by the DAC. We will keep then the volume level at the 'book' level of 2 V pp.(Lo-gain switch position) Having said that - chip volume systems and preamps with opamps belong in home theatre (cheap one) and DEFINITELY not in high end.
LampizatOr DAC should not be used with opamp based preamp, no matter how good. Because the op-amp feedback loops will remove the whole joy of music as delivered by the tubed DAC."
i have an older krell ktc pre I use. it’s all digital menu driven but also discrete devices. it does have a ton of relays though
if Your pre don’t have any settings then yes a passive pre with buffer is good. But a pre that allows to adjust input is also good.
may I ask what model is yours
