Preamp Deal of the Century

Hey Kids,
I'll be looking for Mick's "wonder" at CES.
Competing with the World's competition,
Why should he be afraid?
I know, he just wants to save us money.
Lucky Us!

Tubegroover sir..I question more the method of inserting a new device into one's system than the the mere presence of the device itself. How many of us have re-tuned our system by mix-ing and not matching cables? Was it the color that we just added to the previous red that now made it sound more purple..Cause and effect. I think that it is too easy to hear a difference and everything added makes a change and change is not always recognised for the negative colorations that may result. I feel sometimes the statement system dependent is overused, abused and misused when certain equipment is inserted in the musical chain and bashed because of misapplication or the end user does not understand the inneractions of all the devices involved. I feel much equipment is never really heard as it really is, because of such poor methodology.. Tom

Hey Khrys, just give it a rest.

Everyone is now fully aware of your sentiments, so why not just move on. You are contributing nothing here.

You remind me of MikeCH in the whole Newform controversy.

Theaudiotweak,

I find your argument a bit funny considering your Audiogon name... heh heh.

Anyway, you have to remember that all audio components aimed at the retail market (in general) are designed to be sold at a particular price point. Even Mick's preamps. Also, you need to remember that all tubes are not equal. Different tubes (of the same tube type), sound different. Now, many times tube designers will use some of the least expensive tubes they can for their stock product (to get the price down ofc... excellent tubes can really inflate the price of a particular component).

I would be the last to say that any tube sounds better than the stock tubes of tube gear. I would also not say that more expensive tubes will always sound better than less expensive tubes. I have a tube DAC that sounds better with $50 Siemans Falcon 6922 tubes than $150 Amperex 7308 premium quality white label tubes. However, both of those sets of tubes completely blows away (sonically) the Russian stock tubes the DAC comes with.

The inherent thing about tubes which is both their advantage and their bane is that they do add distortion to the signal. The more tubes a signal is run through, the more distortion that is added. No way around that, that I know of. The great thing about tubes is that in general they add mostly 2nd order and 4th order distortion (mostly 4th order). This distortion is picked up by our ear as more of musical qualities than anything else. Solid state on the other hand adds mostly 3rd order distortion. 3rd order distortion is picked up by our ears as not musical at all.

The problem, Theaudiotweak, is that tubes are funky devices. Saying that a tube piece must be 'heard as it really is' is like saying the best time to take a picture of a race car is while it is going 220MPH. No matter what tubes you use in a piece of audio gear (be them stock or some of the best you can buy), the sound of the tubes is constantly changing from second 1 they are installed and the devices is turned on. It is a type of performance curve they follow during their lifetime which is constantly changing and eventually ends in the tube not able to function. And after your stock tubes need replacing, what are you going to do? Get some more of the same tubes? You can... but you will not be guarenteed the same performance of your original stock tubes. Because, in general no two sets of tubes (even the same make and model) will necessarily perform the same.

Thus, people tube roll because their is a distict possibility they can achieve better performance from different tubes then their stock ones, OR their stock ones have gone kaput and they need new tubes (thinking that different tubes might work better than stock or maybe their stock ones are not available on the open market).

Theaudiotweak, you sound like a solid state guy.

Gotta run.

Theaudiotweak, I suspect most of the people here have gotten past the stage of mistaking better for different. Although sometimes it can be hard to tell. With equipment quality such as this it is easier to discern the difference... if the rest of the system is up to the task of revealing it. Which I guess goes to your point. But I am aware of at least one other user here who's system definitely is up to the task. These guys aren't swapping tubes just because they can.
