Yes, there is a noticeable difference in general (more expensive violins will have a much smoother and warmer tone), but, at the risk of sounding bigheaded here (which is something I'm not), the big difference comes if you have the skill to play in the really high positions.
Don't worry, you don't sound bigheaded, there's nothing wrong with being good at playing an instrument

On the G string for example, on a violin costing say £2000, the tone becomes woolly and even quite rough sounding beyond 6th position. On the E string the instrument sounds tinny/thin and fails to sing once you get past 6th position. The A and D strings also sound woolly and the tone loses definition once past 5th position.
OK, so given the highest I've gone is a 3-octave G major scale and my bowing technique is frankly appauling that would explain why I haven't noticed

This in hand, I'll save my money for as expensive a piano as I can reasonably afford, instead....
Thanks for the information.
