Sorry, but when I do it, it's deemed personal. I got a warning for it. We know full well what we think of each other, no need to spell it out and involve the mods or admins.

Their is no personal feelings against you. Just wish you were happy so you'd go away to some other thread in need of your help in the name of science.

@kenman345: I'll definitely set up that meeting. I'll bring my Sennheiser HD25-1 II, and my Sony MDRV900HD. I only use hp's, as I tend to get major discomfort & other ear issues w/iem's. And I luv iem's btw.

Just wanted to say thanks to Skamp for NOT going away.  I get how he rubs TP owners the wrong way by questioning what they hear, but as an objective 3rd party with no personal bias towards/against the tera player, I'm interested in how the TP measures.  Measurements will never provide the full picture, but if I were to buy a $1,000 device of any sort, I'd want some data on it.. not sure why there's so much resistance against gathering such?

 

Looking forward to suicidal orange's report when he gets it straightened out

and Kenman, just because you define what a "fool" means to you does not make it any less rude.

For the record, I don't claim that the Tera Player can't sound great to some people. Everyone's tastes and sensibilities are different, and fair game. I wont tell a Tera Player owner that he's wrong to appreciate it (if I did, I don't remember it, but I apologize in advance). Besides, whatever faults I can find, don't necessarily apply to their gear or their tastes. Also, I always use the same EQ, with recessed mids. That's definitely not "high fidelity". So I can't really criticize people's tastes, can I?

All I want is objective measurements that everyone can judge within the confines of their own requirements. Whatever choices people make after that, is their own business. I also want that newbies be well informed. If they decide to buy a Tera Player after having been given 100% complete information about it, then good for them.

Yes, I get it. I am not saying he should leave this thread now, I merely was saying I am looking forward to the day the measurements are out there so we can get back to the important things, like how it sounds. Sorry about the fool comment. It's been clearly figured out by now that I meant nothing by it other than we have a difference of opinion in perception.

This thread is why I love head-fi. I am loving my rwak100 but I am anticipating with even less patience now the arrival of my TP. I was a measurements guy a long time ago, but now firmly believe we are measuring the wrong parameters and/or don't even know what the correct ones to measure are. Will report back. Phones to be used with both players are ie800.

Low impedance, direct coupled output with no capacitors between amp and headphones, so that the output can run straight down to DC (zero Hz). And a multi-bit DAC is capable of DC :)

 

So, I made Tera-Player prototypes which were running amps in parallel (to lower impedance just like on the Attraction DAC) and used an active virtual ground (8 OPamps in total) to eliminate the output capacitors. Also, there were no resistors in series to the output.

 

While the sound of this configuration was not bad, it was not really good either. I had the sense of the music coming from inside my head, with lack of dispersion and soundstage. It also sounded kind of brutal, just like: 'see how great everything is under control'. The flow of the music was not good, it was sounding too controlled. It was as if the feedback of the amp was forcefully controlling the musical performance and it reminded me of my experiments when I did the SPLIF amplifier topology many years ago.

 

I was getting better sound quality from other Tera prototypes which had a much simpler output stage and were using output capacitors and I tuned the output resistance for best sound, as said earlier. 

 

In order to see a flat curve under load, you'd need of course a low output impedance. But that curve is a voltage only, and is not necessarily linear to the acoustic output of the monitor in terms of sound pressure.

 

Also, I thought and still think that many of those IEMs on the market are really short-lived, and most of them are made to do at least something with an inferior input. In other words, make them work with mp3 players and smartphones, give more bass, be louder than the others. These things may not necessarily be designed to sound best with a stiff output.

I'd have expected this response by Charles to be satisfactory, especially for a person who has heard the product.

I can offer to Head-Fiers a chance to have at least a quick listen to Tera Player when in Brussels (if mutually acceptable timeslot will be found).

I'd encourage the testers to provide for a glass of wine or beer to help me bide my time while the test is carried out.

 

P.S.

For my liver's sake I hope this will not be a frequent activity...

I've heard good things about the IE800's. (I don't care nor know how they measure)

I second this program in New York.....give me booze, I will provide Tera.....Or we can both drink and use the dual-headphone out......it's a great feature

Thanks for the explanation Charles. smile.gif

Just name the poison (Grey Goose perhaps???) for when I can get out to you. I'm quite a light drinker nowadays, so the leftovers will have to remain with you.
