You still have any of those books? Mine are all destroyed by termites None of those titles ring a bell for me now.. Kind of sad that I kindda miss them now. Will go to a bookstore and ask around, and pretend it's not for me.. :ninja;

Stupid me.. Or online!!!!! hee hee.. 7-12..

I have a few from the 70's Treblid and I still enjoy them although I haven't seen any of the modern iterations.

And regardless of your age; never make apologies for something you love or enjoy. If a certain thing brings you pleasure then it shouldn't matter to anyone else.

I will inevitably occasionaly misconstrue posts, as would occur with most people I would think.

My policy is to reply in detail to newcomers or to those who are in the main precise and logical and on point but who have stated something I feel I can shed light on.

I tend to ignore posts that contain bluster, invective, obvious internal inconsistencies, make simple errors that I imagine most other posters would see immediately; those who repeat a point that has already been explained; and posts of those who have a history of responding to suggestions with animosity, lack of understanding, or a tendency to spiral outwards on tangents.

Also if a person appears to me to be completely on the wrong page I will tend to select just one or two aspects that I feel are crucial; rather than filling the thread with a detailed critique of all aspects of the post with which I disagaree.

For example in a thread about the merits of SACD I was told on about 20 occasions to go and listen to SACD. I did not respond to each such suggestion. I felt it sufficient that I had pointed out that to do a comparison between a stereo SACD and a stereo CD you needed players that could play back the channels at the same amplitude; so you could blind test them. I also pointed out that blind test results that had shown an inability of the human ear with the music being played to distinguish between 24 bit audio and a well dithered master at 16 bits; also the lack of support for higher sample rates being audible.

I could not repeat this every time I was told 'just try it' or that 'food tastes different and so too do hi-fi systems'. The 'just try it' exhortation seems to be a war cry or mantra in this part of the forum. A panacea.

There are those who become distracted by semantic or minor exceptions and argue about those aspects excessively, rather than constructively responding to the broad thrust. If that happens too much it can become dysfunctional. There are others who consistently fail to comprehend. A lot of people who fail to comprehend post only sporadically, so do relatively little harm to the rhythm and flow of a thread. It is an open forum and everyone is entitled to his or hert say.

In summary, dysfunctionality tends to arise when someone posts copiously, but non-constructively.

Fair enough. Good post and thanks for taking the time...........

Sure you dont need my agreement....but I completely agree with you, mate!!! Sometimes I am diplomatic about it...other times, I just swear under my breath!!!

Wow.. I'm pretty sure those will be worth a fair bit of money to collectors?

It will be more an embarrassment (something I can't really help I guess) Online is more discrete This is something that wouldn't work with ebooks..

Thanks to you and simon for that list and name. Couldn't have remembered it otherwise. I do appreciate that.

Sorry to the others for the off track, now let's talk about differences in power cables via BT... Wait.. Seems we aren't talking about that anymore...

[ajm1503559545]

Oh Dear. This is getting a bit personal now. Your making an assumption there about my intent (and reading to much into it!) and you're getting into personal insults so I'll leave you to that. I'm not sure why you've taken such a personal exception to me......but accept this as you're right. I can assure you that the feeling isn't mutual and I have no problem with you. Anyways I've obviouslly offended you so sorry about that.

EDIT: BTW (not speaking for Al as don't know) but when I made reference to KIAs you were not in anyway someone that I was refering to.........

Sorry, I really don't mean to get personal - just a little miffed at the inference that one side of this "argument" have been a pack of unreasonable, insatiable fun police. And really, you can't expect to claim you're staying out of something when you're having sly digs at people in other unrelated threads.

But there's nothing personal about it - it is after all just an internet forum

They can fetch a bit of money depending on the rare ones Treblid. I'd never part with them though. The other ones I have a few of are Photonovels. These can fetch really big dollars if they are in perfect condition. In that list you'll see 12 episodes of Star Trek:TOS - I've collected all of them & the 2 movie ones. Some I found at jumble sales and fetes for $2.00. They're worth quite a bit more than that . They were very popular in the 70's before VCR hit the market.

If you have any questions about Collectibles feel free to ask Simon or myself. We've been collecting different things now for about 25 years (Mostly film/movie/comic related).

I can assure you I did not spend countless hours on the keyboard. I still get my dayjob done. My trophies earned in GT5, my daily listening, etc done while doing all this...

OK, instead of gold I'm now getting bronze.. But I hope it's the game getting "harder" and not because I'm distracted..

Nice sidestep of the issue, the fact remains, you spent far less time doing the tests than you have spent since defending the fact that you didn't spend enough time doing the tests.

BTW the "Bang" was because you find recording results tedious, in comparison to defending those unrecorded results for 50+ pages, which you find somehow not tedious.

Cheers

every post thats worded like this directly towards a particular member is going to have to draw a response, even if only out of courtesy, and thus another page gets added to the total

one cannot then complain about how long someone else spends behind a keyboard if posts are worded so as to draw a response ??

Personally Im not complaining, everyone knows my attitudes towards free expression, and you cant get any free-er than a forum

how do you spell free-er ?

Nah treb's better than that, he's shown extraordinary restraint he won't fall for such obvious baiting, he can see the ying and the yang, you can't punch a silk sheet

Thanks , only in my online identity. Real life I'm quite different..

I think I've used references before about punching a shadow. And how it wouldn't hurt me at all, but only hurt the guy throwing the punches.. Now I'm not so sure. The video is pretty cool...

Esp for something as controversial as this..

[Once was an audiophile]

I am no expert on valve amps but there are many factors which could have caused this.

From what I have seen and read the KT88 amps typically do not sound as good as the EL34 amps sure the KT88's can put out more power but at typically at the expense of sound quality.

From what I have seen of the cheaper ;chinese; valve amps the transformer is one of the biggest influences in sound quality. There are many valve amps using cheap steel cored transofrmers which attenuate the upper frequencies and also attenuate the very low frequencies resulting in a poor frequency response. Without measurements this will not be possible to confirm.

That being said as per above there are many many factors which can cause any amplifier to sound bad too much or too little bias current, ac coupling capacitors, feedback capacitors are just to name a few indivual components which can effect the sound output. This is no different to a SS amp or DAC in this regard.

IMO regardless of what speakers you are using and the room and or treaments you are in if the electronics amp DAC, interconects isn't good it will never no matter what you do sound good.

the kt88 doesn't use chinese transformers. the YAQIN MC10L EL34 x4 (uses japanese made transformers) Class A Integrated Valve is very heavily modded and very good results for the $$$ invested.

regarding kt88 valves vs el34 both can be great and crap depends what parts are used or circuit.

below is the el34 YAQIN MC10L

Input Power : 110V-240V AVAILABLE

Output Power : 52watts x 2 RMS "8 ohm" Class A

Lose True Degree : 2% "40W"

Frequency : 20Hz---60Hz "±1.5dB 10W"

Signal/Noise Ratio : 85dB "A Weight"

Load impedance: 8ohm or 4ohm

Signal Inputs Level : 300mv

Audio Input : 4 groups

Audio Output : 2 groups with 2 x GND

Input Consumption : 250w

Weight: 23 kg

sounds nothing like the specs above the top end is very dull in stock form problems are binding posts ,female rca's valves,internal wiring,capacitors and resistors.it has potential to be a good amp if the right combination of parts and valves are used.

also the volume control is crap.

I'm no expert, and I will leave this to others to answer in greater detail. However I will make the following broad observations:

[*]Whilst loudspeakers and room acoustics may need to be juggled to get optimum audible results, in 2011 the usual design philosophy for a power amplifier is transparency.

that is the goal for manufactures but in the real world it doesn't happen,even 15k amps require modds to perform better

[Once was an audiophile]

It strikes me that you are operating with one hand tied behind your back if you refuse to acquire equipment for checking frequency response, and distortion, and yet are in the habit of repairing/tweaking audiophile amplifiers.

It could be that both valve amps deviated from a flat frequency response in the audible range. If they deviated to a material extent, they acted not just as amplifiers but as tone controls.

Given your considerable experience in the audiophile world to date, don't you feel you could achieve even more with test equipment? Even if it were only used occasionally?

one hand behind my back i can get more from a valve amp with one hand behind my back then you can measuring it,its not all about frequency response.

post your avr frequency response and thd i bet your avr is better then my amp dont worry about specs they are just a guide.

I've seen some of Blades collection in person and it is spectacular!! After blowing me away with his HT system he then showed me some of his movie collectables, gobsmacked is a fairly fitting description of my reaction. After this i was shown the front door, to this day i cant really remember the next 30mins or so, i really wonder how i managed to make it home safely that night . Sorry for OT, go 2K!

Which is understandable I guess as its frequency response is only from 20Hz to 60Hz "+- 1.5 db at 10 watts ".

So much for 'Class A' valve amps.

That is prob a typo.. 60kHz... i assume.. His point is that those measurements don't actually tell you how good it sounds..

Look at the freq response of my amp (same model not not my exact unit: here. frequency response at 2.83V into: simulated loudspeaker load (green), 8 ohms (red), 4 ohms (blue), 2 ohms (magenta). (1dB/vertical div.) . Other measurements here.

It only looks flat because of the Y axis.. For all intents and purposes it's flat, but it still does not tell you how good it sounds. All it tells me it has the bandwidth to go all the way to 100kHz -3dB. But it still doesn't tell me how good it'd sound.

Unless you're listen to a reference test tone, looking at these measurements you'd never really get to know how good they are, it's a rather useful guide though, but it's not everything....

I did understand it was a 'typo'.

Listening to reference tones through audio equipment is a fruitless exercise in evaluating its audio capabilities.
