I suspect that there are a lot of products that are good VFM in mechanical terms. Rega for example produce a whole range of kit that looks great value on paper.
But the caveat will surely be how one determines the quality of the sound reproduced. There are, after all, plenty who think nothing of spending £1000 on an interconnect cable.
I have always described HiFi costings as a simple graph, rising steeply to a 'shoulder' and then rapidly levelling off. Anything beyond the shoulder is poor vfm and out. Low down the curve, at it's start, sound is compromised. The kit you seek lives ON the shoulder I think, and the cost of the shoulder depends on what kit the graph describes. For example, speaker cable per meter runs from £1 to £1000. But the shoulder is around £10-20 range....it's a very low curve.
Loudspeakers however may start at say £150 and rise to £100,000 but I'd put the shoulder between £2000 and 5000...that makes a slightly different looking chart.
If I were to name some shoulder dwellers, I'd name Rega, Dynavector, Sennheiser, Yamaha, ATC, Project, Onyko and Denon.
