About 10 feet sir...I have a wooden table with a thick glass top in the centre but I keep it towards the system side unless we have guests coming over... The dynamics are much better than the Harbeths and so is the clarity... The mids have still not opened out as much as I would have liked but am told that the break in is about 150 -200 hours and maybe even more.. I was away for a month and a half and so the speakers have just 100 hours of playing time..
Now the upgrade options become very limited and costly and I think I will stick to these unless something really nice at a very very good price comes along... Not spending anymore money on speakers and the DAC atleast...
Want to try a tube amp and a digital amp to see if they make much of a difference to the sound but overall quite happy with the setup...
