deepak Posted September 20, 2012 Report Share Posted September 20, 2012 Thought I'd start a thread to discuss these fine (and other solid state) amps. I'm interested in some 100 watt or greater amps. I love reading the Pass DIY forums and seeing all the cool stuff Nelson comes up with. Unfortunately I have a love affair with pain in the butt to drive speakers so I am left with mostly their commercial offerings. My first question is what would be the big difference between an Aleph 2 and XA100.5 as far as sound goes? And about the XS150, has anyone heard them or have insights into their design? Do you think any of the Aleph or XA.5 amps can provide adequate voltage for V hungry electrostatic speakers, especially on very dynamic music? That's all for now Quote Link to comment Share on other sites More sharing options...

Nebby Posted September 20, 2012 Report Share Posted September 20, 2012 Aren't the heatsink demands for the F5 turbo rather...serious? Quote Link to comment Share on other sites More sharing options...
deepak Posted September 21, 2012 Author Report Share Posted September 21, 2012 F5 turbo! You are one sick dud Also it's probably the least interesting FW amp to me, personally I am more interested in the amps that are more to the FW ethos. Excited to see where this SIT stuff goes, though sadly I've seen Nelson nix the idea that they will get used in the higher power amps.

luvdunhill Posted September 21, 2012 Report Share Posted September 21, 2012 Find Pano's thread at DiyA on "how much power do I really need" and answer this question. The reason is, this will tell you how much voltage swing and thus how high of rails you will need. For what it's worth, any First Watt design can be adapted for more voltage swing and more current. I'd think the Aleph2 would be pretty similar. I'd recommend the Aleph J-X or one the Burning Amp series amps. Quote Link to comment Share on other sites More sharing options...
RudeWolf Posted September 21, 2012 Report Share Posted September 21, 2012 (edited) For my 1*102W needs I'd build an End Millennium. Simple enough for me not mess up (yeah, right) and enough juice for 89db'ers. Some of the local guys praise the design and sound. Also none of the parts seem too unobtainable. Cookbook with less bullcrap than the article linked above. Just my two imperial septims. Edited September 21, 2012 by RudeWolf Quote Link to comment Share on other sites More sharing options...

swt61 Posted September 21, 2012 Report Share Posted September 21, 2012 Many people don't know this, but it was just one man in Nome who decided to build an F5 turbo, that started global warming. 1 Quote Link to comment Share on other sites More sharing options...

Hopstretch Posted September 25, 2012 Report Share Posted September 25, 2012 I've been thinking about getting an INT-30A to replace the Exposure in my office system. Just looking at the damn thing gives me half a chubby. Quote Link to comment Share on other sites More sharing options...

spritzer Posted September 25, 2012 Report Share Posted September 25, 2012 That has to be the most powerful 30W amp in the world so I think he'll be just fine. Quote Link to comment Share on other sites More sharing options...
luvdunhill Posted September 25, 2012 Report Share Posted September 25, 2012 (edited) Or get the 150 and go push pull. Edited September 25, 2012 by luvdunhill Quote Link to comment Share on other sites More sharing options...

deepak Posted September 26, 2012 Author Report Share Posted September 26, 2012 Someone that has high efficiency speakers needs to take a flier on the SIT-2 (heck maybe a K1000 user even) I'm pretty excited that Nelson said in 6moons the SIT-1s might make their way into the higher power Pass amps Quote Link to comment Share on other sites More sharing options...
