I started reading this thread a few days ago but due to me having work done around the house I've found it difficult to sit and have a proper listen to my new Rothwell Headspace.
I can recommend the headspace to anyone thinking of trying 1.
I'm not good at putting down on paper what I hear to be honest but I can say that it's a very very good and as I said to Andrew via PM, it seem like the voices are being thrown straight at me. I've also noticed the guitars sounding much more richer, Bass seems much better too.
I was selling my KEL84 due to the lack of bass it was producing but after a few nights listening I've decided to remove it from sale because of this. It all seems to be working very well together.
Great work Andrew and thanks for the recommendation Marco
I'm using the following setup at the moment....
Nottingham Analogue interspace.
Jelco 10" SA 750 D
Denon DL103C1 paratrace re-tip

Rothwell headspace

Hope this helps answer a few questions for the OP
