Here you essentially omitted key aspects of the equation and missed out some key points. As Ken cleared up (power consumption being one of them).
Here you run with the idea of sloppy bass (when those who have used it have said otherwise) and a complete cut off at the 40hz disregarding the idea of just the small drop off (or increase).
More conjecture. The tube as stated by others and in the data sheets, was testing under extreme circumstances, not ordinary one's. The 100,000 hour figure is an estimation (perhaps a bold one). In the same way car manufacturers will extreme test an engine and then calculate the final life span to be however many times the actual test period. You need to understand this.
It is not 25% of the power of an iPod. You just did an underestimation of the figures provided.
There is no cut off at the 40hz mark. You are running with sensationalist assumptions yet again.
Even more conjecture and false claims. With your very little and flawed understanding of electronics, testing methodology and heat (as can be surmised by your posts) you jump to the false conclusion that the tube is used as little more than 'decoration' and that the tube isn't actually 'working'. You really seem to have it in for ALO and this amp.
Then how do other portable amps do it? With magic and fairy dust?
The first bolded part is just laughable. Perhaps with your very flawed, ignorant theories and understanding of these things yes. Second bolded part, we're getting closer.
The last bolded part is just pure trolling if you ask me. Even more shocking considering it's from a mod.
It is completely feasible. The manufacturer tested at extreme conditions and mentioned that these should not be taken as the norm, yet you are ignoring this and running with the extremes.
Also, in response to your post about the cut off at 20hz to 40hz I responded by testing every frequency for you, a post that you completely blanked (not un-expected). You are choosing to ignore facts and posts from people who actually own the device and are instead running with flawed theories or inaccurate comprehension of the details outlined. The 20-40hz response is + and/or -, so it's not necessarily even a cut off, it could be an increase. Even then, 1db is trivial.

No disrespect to you Eric, as I do appreciate some elements of the aforementioned posts, but based on all the above and more, if I was Ken I honestly would not bother to even respond to any of your posts further on the discussion. One question I have for YOU right now is, are you even going to buy one of these amps? Because it almost seems like you've had it in for the amp/ALO from the start of this thread and have no personal interest in the amp itself.
There is literally no reason why he should have to post frequency graphs to satisfy your negative curiosity. It is absurd. You can take the opinions and statements of mine, Ken's and other people (who are actually using the amp), that there's no cut off. I posted a results of a basic test, I honestly think at this point anything further is getting in to the realm of obtuse and unnecessary.
This is turning in to a sensationalist merry go round of epic proportions.
The truth is some of you may never be satisfied with the answers and have countless more every time. I would argue that it is now time to end this hyperbolic tact, one that is taking the thread off tangent, and let the real discussions about the amp itself and impressions take precedent. Any further questions you (or anyone else) have, should imo, in the interests of removing clutter and conjecture, be taken straight to Ken via PM's or emails and then should you see fit, you can post a summary of his responses here at a later date. Anything further, as mentioned, is de-railing from the actual meritable elements of discussion.
Why the insults? Have I insulted you?
First, power consumption is only marginally relevant. I want to see the power output figures. My interest stems from claims that this will drive anything and will overpower IEMs. If that is true, some numbers would clear it up.
Power output is listed for other amps at the ALO site; why not this one?
Power output and frequency graphs are provided by almost every manufacturer for almost every product. Asking for them is not in the least unreasonable.
If you would like to perform your own tests, build a dummy load and use a DMM to measure the output. Run that through the power equation and you'll have an answer.
I sti take exception to the estimate of tube life. A hundred-fold increase is astonishing. Even if something might run for 2,000-3,000 hours under light conditions, you don't get 100,000 hours from it unless it is barely being run at all. If you barely run something, you don't get anything out of it. That's the point.
If you're keen on testing, open it up and measure what the tube produces. Find out for yourself. If you find a huge amount of power developed without consistent levels of heat, you might want to contact some scientific journals.
As for your other points:
1. Yes, I am
quite frank with people and unafraid to ask questions. I'm a lawyer and a landlord; strongly opposing opinions come up daily. I have asked a number of manufacturers - in person - for stats on their amps. I've never seen one who acted insulted by those questions. Every one is immediately forthcoming and will talk for hours about their design, design philosophy, and you'll have an interesting conversation. Try it sometime. Most are really nice people who will tell you everything.
2. Forums are for public debate and discussion. If there are questions, criticisms, concerns, whatever, you talk about it openly. Amplifiers have always been discussed critically and technically here. Please look at the thread about the Objective 2, the design is fully picked through. Same with a few hundred others. There are loads of negative reviews and criticisms here. I wouldn't want it any other way. Just like how you openly criticize me. That's fine. I'll be happy to answer.
3. I started asking questions because I have an interest in tubes. I use them all the time, work on my projects and read about them. When I see claims going against everything I've read, heard from others and personally experienced from working with them, I'm going to ask questions. See points 1 and 2, above.
Thanks Vinnie!
