New amps with SP Tech Revelations

IF you wanna try something different try the apl ua-s4.
It can drive pretty much anything. I used to own spectron iiise with vtl7.5 and the apl is far superior imho. Comes with money back guarantee if not satisfied.

Thanks...but it seems to be only "your" amp; i.e. nowhere else on the Web is it mentioned except by you (on APl forum and here). And I'm in the US and Alex is in Eastern Europe. It also seems to be an integrated...not at all what I'm looking for. Thanks though.

Hi Ted i agree its not in big circulation but if you read more on apl forum youll find more users. When volume is turned up full its bypassed and works like regular amp, you can order it without volume as well. Apl will ship to us no problem and alex visits california to do local upgrades as well. Its not huge company and if you own sp tech or used to dealing with smaller operators. So soundwise im certain it sound be an upgrade for you and as i said if your not happy with how it sounds you can just return it for a full refund.

Hey Ted,

I now have a pair of Revelation MK-V's that I modded with the advice of Robert Maicks at Star Sound.  Made a very noticeable improvement in clarity and dynamics throughout the frequencies ranges.  I also have the Sistrum SP-101's under them.  Removed the parts between the speakers, cut a 2x6 down to a pair of 10"x 5" boards 1"H.  I cut the inside of the board to 3.5"x 8.5" so it matches the rectangular hole near the back of both cabinets.  I sealed it with silicone caulk under the board and screwed it with 2" coarse drywall screws.  

Robert sent me 14 inverted couplers, four 1" Audio Points threaded,  four narrow 1" APs threaded, and 8 brass inserts.  At the bottom, I installed the couplers to go on top of the Sistrum points after recessing the space for the fat part of the coupler to lodge.  On top of the bottom cabinet I drilled into it so the inserts could be screwed in.  Under the bottom of the top cabinet, I did the same corresponding thing as the bottom by recessing the space where the coupler will lodge so that it will fit directly on the point.  

Once you glue a flat strip to the top of the 1" thick board, you are ready to put it all together.  IF you measured carefully, the coupler will fit over the points that are under them.  This also holds the top cabinet in place so it has less chance of get knocked over.  The top cabinet MUST sit flush on the board that seals it to the bottom cabinet.  It also must sit solidly on all the coupler/points.

I have the Nuforce Ref 9 V3 SE mono amps with the latest power supplies Bob Smith has been using that have 500 watts power per side and sound wonderful in all ways.  Also have a TRL DUDE preamp that has hoppin' dynamics, powerful bass, and very live sounding overall.  It's a great combo with the Revelations.  

I'm the only one to do this mod, but if you have pretty good tools and are accurate, you can do this.  It's well worth it as the sound jumps a couple notches more real.

In the 3rd to the last paragraph, that should read glue a felt strip to the top of the board.

Last sentence in the post would be entirely accurate saying there is now much better clarity and details. The bass hasn’t been to the 10 day since the Revelations were put on the Sistrum platforms so I can only guess just how good that will be. It was the strongest pre-mod part of the spectrum, so I’m sure it will become spectacular when I receive the upgraded amps back fro Bob S.

P.S. To sum this up quickly, the whole project has been very exciting and the reward MAY be even better. Bob, I love your speakers and the Star Sound treatment bumps the entire package up significantly.  

It's been quite a while but a friend of mine had a pair of SP Tech floor standers (not sure which model) and he had great success driving them with a set of Theta Monoblock amps and Gen VIII Dac/Preamp. The Enterprise Monoblocks have dropped in price dramatically and can usually be found for under $4K a pair. I owned a Theta Dreadnaught in the past myself and it was a great sounding amp. 

I am unsure what the status of Theta is with regards to servicing their products but they might be worth a look. Good Luck!
