$18k Tube preamp for large scale symphonies please

"best preamp is NO preamp"
For some this may be true(system dependent).
In some systems the lack of a preamp may'not' be enough, as many find improved sound quality with a 'good' preamp in the signal chain.
This has been covered numerous times and I doubt any minds will be changed from either point of view.Which ever direction works best,follow it.

From my experience with NO to all types of preamps, it's a BIG POSITIVE if using the CORRECT active preamp.

An essential feature for me in a linestage is well implemented support of balanced inputs and outputs. By "well implemented" I'm looking for low output impedance and, if possible, galvanic isolation of the outputs such as via transformer coupled outputs. Since I like the capability to bi-amp, having a volume control on one of the outputs would be a great bonus. Even if you don't need these features right now, these may be something to keep in mind if your systemm veers in that direction.

Another overall system requirement, again for me, is the ability to reverse absolute phase on the remote (and yes remote control is a must-have for me). Ideally, this would be provided by the linestage, but failing that, the DAC would have to provide the capability. In that case, however, you're left without the ability to remotely switch polarity for non-digital inputs. The impact of absolute phase has become more important as my system has evolved.

I'm also evaluating linestages and appreciate all the input to this thread.

Passive preamps are colored just like any other component. If the coloration fits your system thats what counts.

If the preamp is fully balanced, doing phase reversal is a non-issue. We have had one our our preamps for the last 24 years.
