Members xtchc1978 Posted March 11, 2009 Members Share Posted March 11, 2009 Kind of cool but it just has some tubes in the preamp section, not really a tube hi-fi system. I agree more of a marketing gimmick then anything else. Link to comment Share on other sites More sharing options...

I only know two "audiophiles" (both of them are nuts IMO) but both of them have very expensive tube amps. Link to comment Share on other sites More sharing options...

I agree more of a marketing gimmick then anything else. This. I wouldn't be surprised if the preamp was made up of 12AX7s running at starved voltages and back-lit with LEDs. Of course, the side effect may be that this will reinvigorate interest in REAL tube-driven HiFi, and lead to the resurgence of well-designed, affordable, all-tube stereo gear. A guy can dream.

Probably. Although, in the reviews some people complain about a warm-up time... so the tubes are definitely doing a job there. Link to comment Share on other sites More sharing options...

Members metalfanat1c Posted March 11, 2009 Author Members Share Posted March 11, 2009 Cool. Speaking of this, how do speakers made from neodymium sound?Neodymium is a magnetic substance... so it reacts against the voice coil of a speaker in a similar fashion to ferrite, but these speakers are typically a whole lot lighter and take up less space. Typically, the neodymium magnet will have a slightly reduced magnetic range, which means in a driver designed with excursion and decent bass response in mind, the voice coil will leave the magnetic gap resulting in distortion.

Members newholland Posted March 11, 2009 Members Share Posted March 11, 2009 yep.. i audio nerd, and probably nuts. but i'd BET that's lights... i'd be WAY more inclined to see a schematic before i deem it real... i like the ribbon tweets. meanwhile-- neodymium is just a magnet type-- way high gauss/weight ratio. they can sound pretty badass.. i use neodymium compression drivers and they sound good-- but there's a lot more afoot than just the magnet insofar as how they sound!

Members Sixtonoize Posted March 11, 2009 Members Share Posted March 11, 2009 Actually, I found this discussion/description of the tube section and mod suggestions: http://www.tubecad.com/2007/12/blog0127.htm It's halfway down the page. It looks like B+ is 200v, but the signal gets pretty heavily attenuated before AND after the tube stages. The tube stage is a somewhat competent, but nonetheless rather silly affair, with the 12AX7 working in a low-gain, high-feedback line stage amplifier. Interesting, nonetheless.

Members newholland Posted March 11, 2009 Members Share Posted March 11, 2009 lemme guess...vinyl sounds better than cds? ONLY providing you have: clean vinyl, a well set up table (a well protracted arm that's weighted accurately, and not tracking wierdly) a good sounding cart, and a decent preamp. providing those things, absolutely every time. cds can sound awesome. provided they're carefully set up as well. they're just a LOT easier to set up 'cause it's all done for you!

Typically, the neodymium magnet will have a slightly reduced magnetic range, which means in a driver designed with excursion and decent bass response in mind, the voice coil will leave the magnetic gap resulting in distortion. Really? That's odd considering neodymium as a material has a greatly enhanced magnetic range and power compared to ferrite or alinco. It's the fact that neodymium is so powerful that allows so much less of it to be used to manufacture speakers and motors of much reduced size with similar amounts of power.I guess in a cheaply made speaker corners could be cut to use less then the desired sized magnet to result in gaps though, but this shouldn't be the case with a properly designed speaker.-W Link to comment Share on other sites More sharing options...

Members teemuk Posted March 11, 2009 Members Share Posted March 11, 2009 I don't see how adding a preamp tube could make a stereo system more "HiFi". The last thing I want to hear introduced to the signal coming out from my stereos is some distortion or abnormal skews in the frequency response (for "warmth"). That's nice in guitar amps you really want to overdrive but pretty much reduntant and annoying in HiFi gear, IMO. Link to comment Share on other sites More sharing options...

About 7% in today's market... especially with neodymium drivers. The fact is, in the sizes typically used in drivers today, the magnetic field produced is simply not enough. Now in a properly designed speaker, all things would be perfect, would they not? You go to great lengths to prove me wrong whilst not taking notice of the frequency that neodymium drivers are currently designed to reproduce. Most woofers or subwoofers are still using ferrite magnets, whereas a good lot of tweeters are using neodymium magnets. Link to comment Share on other sites More sharing options...
