-- Hi Jeff,
No worries... and I should make this clear to everyone. Without question, the RAAL ribbons are technically superior transducers when it comes to accuracy. However, this does not mean that they will sound better to you.
For example, a good customer of ours came by with his lovely wife this afternoon to audition both the ribbon towers and the NrT towers. He already owns Sierra-1 NrT.
He liked the ribbons and spent perhaps an hour listening to them. We then swapped out the ribbon towers with the NrT towers and they listened for 2 1/2 hours, goosebumps and everything. They went home with a pair of black bamboo NrT towers as this was a sound they were more familiar with and preferred compared to the ribbon versions.
Even with the technical superiority of our ribbons, it still comes down to what sounds best to you, and your 340's use an exceptional dome tweeter
