I don't know if I should rate this highly because its great or low because it caused me to spend an absolute fortune on further Eurorack stuff! This was my initial Eurorack purchase and its been a long, strange, costly and very rewarding road!
One thing worth mentioning and paying attention to is the Doepfer warnings about working with electricity. This is not an all in one/plug and play solution you do have to work with potentially lethal electricity voltages so PLEASE read Doepfers warnings, check out the set-up on their website and read the warnings again! Ask questions on forums and don't just take a chance yourself! Saying all that, it is not difficult to be safe and get a cost effective Eurorack system set-up. If your not confident get a friend or electrician to look over your system. If I can do it anyone can but please be safe! (All this has nothing to do with Thomann who just sell the kit at a very good price!)
So I bought one of these - and then bought another! Once you have set it up and find out if Eurorack is for you or not you will more than likely be buying another (and another...)
This is a well put together kit that with a little common sense is safe and has plenty of grunt to get you up and running. The only issue is when to buy another/a bigger case!
Pros - Everything you need to get going. Plenty of power to get started. Well documented on the manufacturers website. A big online community that can advise and help when needed. One of the cheapest initial solutions to get up and running. M3 screws and bolts are readily available from most home improvement stores should you need more/run out.
Cons - its not an enclosed system. You will need a case. Be careful working with live electricity. You CAN fry modules and yourself if you wire it up wrong and when you wake-up you'll be talking to St. Peter. Be careful!
I dont want to over labour the point but this is not a Happy Ending Kit, a Roland powered enclosure, nor does it have shrouded module connectors - just be sensible and you will have years of fun with this Doepfer kit.
Highly recommended (I couldn't recommend it higher to be honest) - be safe and have fun!
