But I have found the aluminum horns (511B/811B) to sound more lively and sound better with the very low powered amps.

I'm glad that there is plenty of opinions and ideas on what to do with these VOTT systems, that way Tim and Colin can take them all in and decide what direction they want to go.

I may be wrong, but I advised both of them to listen and enjoy them for awhile before starting to tweak those systems. The sky is the limit on tweaking the A7 VOTT, but either way they sound pretty good in stock form.

Dr Bruce Edgar when asked to compare his "Edgarhorn" system to the VOTT's replied that the VOTT's are good at "vintage horn" sound vs his "modern horn" sound. I have had both and like most things in life they both have their good points.

I like wood horns now but still enjoy a good listen to a pair of A7's now and then. For the money though it's hard to beat a pair of used VOTT's if you search for ther parts at their best prices.
