Does anyone have an opinion on this amp?

What are the other tubes worth?

The singlepower is definitely a nice amp, adn that's a nice price.

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.

the toasters are a great value.

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.

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...

Or maybe a Beta-22.

thanks for the info jonL, Ill Start Looking.

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,

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.

Rockhopper Audio is building the B22. It should be a killer amp if the M^3 is any indication.

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.

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

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.

No you are basically correct. 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.
