Tron Convergence, with Firebottle modifications.

Wow, the RIAA EQ on the TRON looks a great match to the RIAA standard on the curves. I'm not a designer, so please excuse me if every audio manufacturer gets them this close. Perhaps others on this forum could share their knowledge or even their data, so that we can all see.

The Tron's not bad but most of my phono stages are considerably more accurate still than that.. +/- 0.05dB in most cases though I normally quote it as +/- 0.1dB

I'm afraid I'm not about to go through the measurements again to make them into pretty graphs though!

It needs to be born in mind though that a reverse RIAA eq network must be used to generate an inverse curve against which to measure the RIAA accuracy of a phono stage. this network must itself be very accurate indeed of course. I guess it could be generated digitally nowadays but I'm a traditionalist

I rather doubt that the tiny inaccuracies of the Tron's eq would be sufficient to have any but a very minor effect on it's ability to reproduce a squarewave. As an aside here, if you pass a squarewave through a reverse RIAA generator (awkward it itself as a certain amount of HF bandwidth restriction must be used otherwise it will try to produce infinite treble boost!) and then feed this through a phono stage under test you should then see a squarewave out... the degree to which it's not square reflects the RIAA accuracy and it's a great quick test that it's in the right ballpark.

yup they are working now.

Yup, same here (now)

The reason for the post was that I've been reading about the Jez, FB and the nva phono stages and was interested to hear the outcome. The Tron has thrown me into further confusion.
I'm using a fairly hopeless Project box with a 1210 at the moment and really don't want to get on the train of box swapping and the unnecessary expense of it all.
Also, I don't drive, so any chance of a show is pretty much out of the question.
So, if nothing else, can someone point me towards the correct thread on here?
Thanks ��

If you don't even know which thread you are referring to, why express an opinion on how the forum is run based on this thread you don't recall?

David,
It might help if you could let us know a bit more - available budget, cartridge and the rest of the system. Also future plans. Is this a final upgrade or have you been bitten by the hi-fi bug?

David,

Your remarks, dragging previous arguments here from a (now locked) thread elsewhere have been removed, which are both telling and unacceptable. Telling, because it indicates that you have an agenda against how this forum is run (perhaps also those who own or manage it) and thus *appear* to be here as an irritant, and unacceptable, because the thread was locked for good reason.

As a newbie, I'm giving you the benefit of the doubt for now, for you to prove otherwise, rather than simply ban you outright. A word of advice: if you wish to remain here, then stay out of forum politics that has absolutely nothing to do with you, and concentrate *solely* on posting about hi-fi and music. The latter is the only acceptable reason for your presence.

Now with that in mind, we'll help as much as we can with any genuine query you have in respect of phono stages, but it's with the understanding that no further reference whatsoever is made to the closed thread in question. Your failure to comply with that request will result in me not giving you the luxury of the benefit of that doubt.

I trust I've made myself clear? Ok, let's talk about phono stages!

Marco.
