I purchased the Revel Studio's18 months ago. Im my opinion, I have not heard anything in the $10k price range that is their equal, including the Dynas which I listened to along with many others both more and less expensive. You did not mention what type of tubed equipment you are using, so I don't know what the power of your amp. While the Revels are fairly efficient and will work well with a variety of amps, they do like power and will easily handle as much as you throw at them. Be aware of one other thing with the Revels - these are highly detailed speakers that will accurately display everything in your audio chain from the CD you play to the components you use to the wires that deliver the sound. If you have poorly matched ( not necessarily cheap vs. expensive ) speaker cable, you simply will not get the best these remarkable speakers have to offer. Transparent Cables are a match made in heaven although I chose the new MIT 750 Magnums which use Oracle technology. One last thing, you are comparing two very different speakers. The Dynas are not nearly as detailed and are built to please regardless of what may be the weakest link in your audio chain. They will also distort as you increase volume. The Revels are built to show everything in your audio chain. I have not yet reached a distortion level no matter how loudly I drive them - I do't know where that level is.
Dynaudio v Revel
I have been auditioning a number of speakers in the $7000 to $10,000 range and due to a significant price break am leaning to the dyns. Never the less I have been impressed with the Revel Studios. It is just that right now the potential price differential is about $3500. I am using tube amps, pre and cd. Any thoughts out there? Thanks!
