Happy New Year 2010 to everyone, indeed. It will be a good year: Putting the finishing touch on my new 105-2 90 litres cabinets, just purchased a second Quad 405 to upgrade and use as a double mono, as well as a Quad 606 to upgrade to 909 specs. Also "cleaning-up" my Hafler D500 power amp. Wink

Quad 707 & 909 amplifiers are cold and lifeless in comparison to the 606, as they use different output transistors requiring higher frequency suppression feedback loops.

The Quad 606 can be further divided between those with the "rock" toroidal transformers and more musical earlier "classical" C-sections.

Grunt isn't everything and some of these expensive kit modifications sound pretty poor in comparison with a unit that's recently visited Quad Service in Huntingdon.

Interesting.

I'd heard similar before but not seen the reason behind it (hifi contains it's fair share of 'they don't make 'em like they used to').

Having owned a 909 for a while I'd have to say I was never really drawn in by it, though it did a perfectly good job of driving whatever I put on the end of it. Am now much preferring 30 Sugden watts to the 110 Quad watts that went before.

Happy New Year everyone. The last 4 days have been pretty productive for me. Just finished the elements of a test cabinet of 220lt that I want to use for trying out different combinations with some drivers, before I decide what I like better.

Will be trying B300 in sealed and vented enclosure, with single and twin drivers (in an isobaric chamber).

The WinISD simulations of the B300 in isobaric configuration and 190lt box tuned at 20Hz seem very promising.
