You could do that but trying to guesstimate how much to turn up the gain to = +5b would be difficult. Most modern AVR have speaker output levels. You can percisely set the SW output level for +2-3db (if using bass management to avoid over boosting redirected bass) or +5db is using "large" speaker (aka no bass management, no crossovers, full range speakers).
Every AVR is different but my Onkyo705 has channel level option on the remote. I rotate through the speakers until SW if displayed. Now my SW is normally boosted +1db (Auddessey EQ compensates for room & distance) so I bump it up to +3db as a "bandaid" solution.
Long term Panny needs to fix this or I will never buy another one of their products. Proper analog output is hard and expensive. Today most 24bit DAC are really not able to resolve more than about 18-19bit. True 22bit DAC are well beyond consumer grade equipment. Digital on the other hand is too easy. 1 is 1 and 0 is 0. Always. Levels should be exact (not close enough).
