lross78550 Posted November 28, 2007 Report Share Posted November 28, 2007 This amp just showed up on "the other web site" Does anyone have an opinion on this amp? What are the other tubes worth? http://www.head-fi.org/forums/f42/fs-singlepower-mpx3-slam-269408/ For the same money i could have this.. http://www.headphone.com/products/headphone-amps/the-desktop-line/2007-headroom-portable-desktop-amp.php thanks for putting up with the stuuupid newb.

grawk Posted November 28, 2007 Report Share Posted November 28, 2007 The singlepower is definitely a nice amp, adn that's a nice price.

n_maher Posted November 28, 2007 Report Share Posted November 28, 2007 For a bit less $$$ you might have a look at the toaster MPX3 that is also listed on Head-Fi. It's listed by cantsleep, who've I dealt with before, and would be worth a PM to get more details. Quote Link to comment Share on other sites More sharing options...

purk Posted November 28, 2007 Report Share Posted November 28, 2007 The toaster MPX3 should have slightly better tonality b/c stainless steel is a better ground plane than aluminum, according to Mikahil. However, the powder coated chassis MPX3 might have a more quite blackground b/c the chasis is more solidly built. Both amps should sound great and should sound great with many headphones. If you decide to pick either amp up, I recommend you to get the ECC1 adapter and upgrade the MPX3 to a high voltage upgrade, that way you can use the 6BL7/6BX7 as output tubes.

Jon L Posted November 28, 2007 Report Share Posted November 28, 2007 Aren't you the Nautilus/Levinson guy? I don't think MPX Slam leans towards that direction at all. I'm thinking something like Grado HP1 (or 2) with a nice Dynahi amp would be right up your alley. If (and when) HP1/2 is impossible to find with reasonable prices, Senn HD600 with balanced cable into something like Dynamight (balanced dynahi) or Headamp GS-X would also be in the kindred spirit...

Dusty Chalk Posted November 28, 2007 Report Share Posted November 28, 2007 Or maybe a Beta-22. Quote Link to comment Share on other sites More sharing options...

lross78550 Posted November 28, 2007 Author Report Share Posted November 28, 2007 Hey wait a min. I dont want to build the damn thing! i have a life, its not much of a life but .... Levinson didnt make me build the 436 mono blocks they just boxed them up and shipped them to me Lee Quote Link to comment Share on other sites More sharing options...
n_maher Posted November 28, 2007 Report Share Posted November 28, 2007 Lee, You don't have to build it, you can usually find DIY amps for sale used or your can commission someone to build one for you. Quote Link to comment Share on other sites More sharing options...

Levinson didnt make me build the 436 mono blocks they just boxed them up and shipped them to me Lee Rockhopper Audio is building the B22. It should be a killer amp if the M^3 is any indication. http://www.rockhopperaudio.com/ Quote Link to comment Share on other sites More sharing options...
deepak Posted November 28, 2007 Report Share Posted November 28, 2007 I should add one thing that makes me wary about the SinglePowers is if the caps that they use are enough protection in case a tube decides to fail and take something out with it. I know postjack's SinglePower PPX3-SLAM killed one of the drivers in his RS-1. Just something to think about. Quote Link to comment Share on other sites More sharing options...

grawk Posted November 28, 2007 Report Share Posted November 28, 2007 I would really like Mr. KG to weigh in on this matter. Using old, out of production headphones makes this a concern. My understanding is that it'd be nearly impossible to have enough capacitance to protect from a spectacular tube failure. It's one of the joys of tube amps Quote Link to comment Share on other sites More sharing options...
n_maher Posted November 28, 2007 Report Share Posted November 28, 2007 The caps are there to remove DC from the signal going to the driver, but they don't at all limit the AC voltage or the current so I'm guessing this is probably what killed pj's RS-1s, not a DC spike. But I'm applying what is rather limited knowledge of this stuff so bear that in mind. Quote Link to comment Share on other sites More sharing options...

I was hoping to get KG's opinion on a method of protection beyond a epsilon12esque muting circuit. Just want to see what the Doctor had in mind, that's all.
