Speakers are easily the most personal choice of any audio component. The differences in presentation are the most marked. Not surprising, really, given how much difference there is between different designs. Compare those differences to something like DACs.
The first NVA item I purchased was a BMU. I was so impressed with it that I called Richard up and asked him what I should try next. He told me that if I liked Cubes then I would definitely like the rest. I ended up buying a P50 / A60 / Cube 1s / SSP / LS6. The cables arrived first, so I tried them with my Sugden amp and Harbeth speakers. Subtle but definite improvement. Then the amps arrived...subtle but definite improvement. Then the Cubes arrived...different league, very different presentation.
Yet, I have helped Richard at shows, and visited shows, where I have seen people walk into the room, see the Cubes, mutter something along the lines of 'Oh, no. I hate those things' and walk straight back out again. Others have sat there for 5 minutes and said 'that's a bit weird'. Others have said 'Mmmm, there's something very interesting here'. Shows are a tough environment, lots of ambient noise, people coming in and out of the room, sometimes less than ideal rooms and acoustics. Richard sold virtually nothing at the shows he did in the last 4 years, partly because of the issues above, but partly because people were being asked to take in two ideas at once - the performance of the amps, and the different (to them) presentation of the Cubes.
Don't underestimate how difficult it is for an amp manufacturer to achieve cut through to also being a successful speaker manufacturer. One of the first bits of advice I got, from several people in the industry, was 'do what you are known for'. Consider these examples...
Naim - well known for amps. Diabolical speakers.
Rega - well known for turntables. Mediocre amps. Mediocre speakers (apart from ELA which used Royd drivers)
Linn - well known for turntables. Mediocre amps. Diabolical speakers.
We will dem the new Cubes at shows, but we will also dem extensively with the types of speakers that most visitors will be familiar with.
