Magnum Dynalab 308 drive Magnepan 1.7 or 3.6?

Ctunney,

You made excellent choices in acquiring the TAD 150 preamp and the Bryston 4BST amp. The tubed 150 should add a touch of warmth and bloom to the ss Bryston's powerful and detailed presentation. It's also a very good impednce match since the TAD's output impedance is 600 ohms and the Bryston's input impedance is 60k ohms.
The new (to you)amp has plenty of power (400 watts@4 ohms) to drive your future Maggie 1.7 spkrs. Do you know the Bryston carries a 20 year transferrable warranty? Make sure you get all relevant info from the seller and contact Bryson to transfer it to your name.
And by buying your preamp and amp used, they should both be broken in already. But remember the 1.7s will require a break in period of several hundred hours before they sound their best, they may sound a little bright initially, but should sound better and better as they break in.
Well, I think I'm starting to sound like a dealer or spokesman (I'm neither, I swear)so I'll end here by just saying again what a great job you've done on putting your new system together. It all looks very well put together, well matched and synergistic on paper but please post again, after you've set everything up and listened to and ejoyed it for awhile, and give us your thoughts. Have fun.

Thank you, Noble. I must say that it is taking FOREVER to get the 1.7s. Just got word that I will get them on the 17th. This will be a total of 10 weeks (!) from when I purchased them. Will update after some break in. But for all you prospective Magnepan buyers out there, be prepared to wait! And wait! And WAIT! Magnepan told me that they are currently quoting 6 weeks for the 1.7s, but this was not my experience...

mine took 90 days last year. Once you get them, take some warhorse pieces like "night on bald mountain" or like that uses full orchestra loudly,set on repeat, turn amp to preferred volume, exit the room, and come back in 10 hours... they are basically stiff when new and need to flex to gain full transparency. 10 hrs won't be enough for full break in but it should allow you not to fret at the first serious listen. Takes about 100 hours to reach full potential and sounds a bit edgy in the highs during initial break in... this goes away unless the edge is really there from the equipment/cables feeding.

Ctunney, I'm extremely satisfied running my MD 308 with a pair of B&W 803. The MD308 is an Amp for life I tell you.
What other components are connected to this amp?

I'm also achieving superb results when biamping.
