FAQs

Please read our FAQs page to find out more.

Do you have a real store?

Yes! We have a store set in a quaint location with plenty of parking even for HGV's! We have a dedicated demonstration room for Headphones/portable audio, 2 channel HiFi and one of the most advanced home cinema rooms in the country.

Can I home demonstrate products?

In most cases yes. Simply contact us with your requirements and if it's on the shop floor - we can arrange a home demonstration.

Do you ship from store?

In most cases yes. We have a store front with products such as cables and smaller products physically to hand. We also have a dedicated warehouse a few minutes away with over 1200sq m of products stored. Some products are shipped direct from manufacturers - as it's not practical / cost effective to store every variant of every product. We are very efficient at stock management however.

Can I return a product?

Yes! So long as it's new/unused and in the same condition it was delivered to you, we will gladly refund you up to 14 days from purchase. Please raise a request via your Account area to start the return process.
