For nostalgic or practical purposes, does anyone still use cassette on the move (possibly a Sony Walkman Pro for the devotee?) As the format of my youth I'm just curious to see how many cassette fans there are still out there!

What are your opinions?

What did everyone choose?

Rfgardless of price, what's your vote?

We're introducing a dedicated headphones listening demonstration suite in our Audio Affair Birmingham showroom and are interested to hear what you feel would be the "ultimate" headphones demo? For example... - Would you want to bring in your own CD player or turntable/phono stage? - Would...

If so, what are your thoughts?

As the Solo MC has been our best selling headphone amp of recent times, we're curious to know if anyone has upgraded from this to something else, and if so, what have you found which in your opinion is a step up?
