I started with the VSM-MM and a solid state amp. I upgraded to the e version (lead free) and the super BAM. After these upgrades I went to the tubed Filarmonia int amp. Each of these upgrades resulted in a noticeably fuller and more relaxed presentation. The bass became more pronounced and better balanced. In the beginning I thought the speakers were a little lean and sterile but now I am very happy with them. The speakers are very detailed and are sensitive to any changes in the chain. I have not heard the VR3. Try to start at highest point in the Merlin chain with the super Bam and e version.
Good listening
