I own the Volare and. PD-171A.
The Luxman has the advantage thar you can mount a cover which is very convenient. A fine piece of mechanical engineering. The Jelco based toneam is a very good performer, very detailed and matching a wide vairiety of cartridges. If you want to grow in the future choose the 171 over the 151 as you can change tonearm basis.
The Volare does not have the same quality feeling. The advantage is that the armboard can be changed and there are a few upgrades you can make. It sounds very neutral. If you want to grow in the future I would go with one of the bigger brothers of Volare.
They both are very capable, but look different and sound different. A matter of taste.
