Problem is that the leads on capacitors act like antenna I think.

Should they be replaced with high quality SMD parts then instead?

What are your impressions?
Be careful what type of caps are used here, I've found some in the PLL can make it sound surprisingly nasty
I'd certainly not use those ceramic disc plates which are microphonic
Its hard finding nice parts in SMD, COG/NPO should be ok for 1N , the 22N maybe harder
