Sub-Woofer?

@gasebose There is a REL-R-328 for sale today for $600. The listed retail price of $2700 seems wrong to me. I recall it being something more like $1800 or so. But, $600 is a good deal if it is truly a 9/10. I own two of these, use them only for music and I recommend them. You would have to talk the seller into shipping it to you if you don't live in Austin. But if you're covering it that shouldn't be too hard. 

Even for music, the T5 and T Zero don't really have the extension to cover the the audible frequency range for a lot of musical content.  

Thanks Astewart! But I'm planning around a slightly lower budget; this is my first try at a sub-woofer and it's kid of experimental. But thanks for the suggestion!

Tutetblimperes, I'm sure you're right. But I'm not really looking for floor-shaking sound; just a bit more bass than I get from my Cabasse Galiote bookshelf speakers.

Appreciate your input!

Understood. A subwoofer used appropriately won't shake the floor much. Instead, it will provide seamless extension from your mains. RELs do this very well.
Happy hunting!

First upgrade the SA-12.  Buy Nichicon I think 30,000uf PS caps (I think the blue stock ones are 20,000uf so go the extra size just be sure they fit in there.  The upgrade the diodes to HexFred, add a filter choke, and then add Caddock output resistors, check the values on the ones on the AC connectors.  Then make a decision on adding a sub.  Happy Listening.
