As the Galileo LE ships with a choice of UEF tuning bullets you can tailor the sound as needed. Two greys will sound "dark" but a mix of one grey and one silver or two silvers will be much more open. I started with the grey/silver and moved on to two silvers as I improved my system.
The LE also responds very well to upgrading the power via a transporter. The CTS is no comparison so if you can afford the LE go for it especially as there are many available at present. My experience choosing the LE over Odin v1 and WEL is on record in other threads
