  • amplification = to tube or not to tube ,that is the question

    tube equipment always seems to be the choice at audio shows , music only applications , what's the reason ?
    surely there are high end companies out there that make pre-amps and amps that could compete with or possibly outperform tubes !?

    What he said. Do a build thread.

    See what happens when I get into a thread, and start talking about stuff? Another big project is the result. I blame you all

    I won't bore you with the details.

    Good points, Washuliu. My experience with Korg NuTube is that, yes, microphonics can be an issue but can also be readily deat with. As to low gain, that is not correct, and you can read Nelson Pass's buffer article. 16DB of gain. A guy I know has a 1991 Ferrari. I would be hard pressed to tell him his car and its engine and transmission are outdated, inefficient and obsolete by today's standards. Looks great and drives pretty damn nicely if you ask me.

    Some of these responses is a good reminder why this a speaker forum not an amp forum. For people posting under 60, please know that tube designs have expanded over the years and tube amps now sound whatever way you prefer - 'warm', 'transparent', 'accurate', hybrid, SE, push-pull, OTL on and on - the whole spectrum is covered. B*****ng about tubes is like saying paper drivers are nostalgia-driven, distortion-prone, over-priced and just not competitive with drivers made with newer materials.

We can argue which type of tubes people think sound better or, in SS, who are the class A aficionados (Pass Labs), high power (Boulder Amp), Class D, etc. Hey, whatever your ears like is fine with me. I heard a $100,000 set up of Boulder Amps and their pre, Focal speakers and mega buck CD and turntable at GABF several years ago and thought it sounded dry and lifeless. Andrew Jones SS powered speakers for 2K at GABF last year were brilliant. My friends old Sonic Frontiers 6550 tube amp and matching pre through a pair of old B&W Matrix 801's was one of the best systems I have ever heard. Sigfried L's LXMini with Emotiva mid level amps was one of the best systems I have ever heard at GABF. I was blown away by Audio Research Tube and Pre Amps and CD driving a pair of Wilson Watt/Puppies. I can't afford that high end stuff, but my Hypex amp through my SEAS DIY monitors sounds good. it's better with my EL34, but is in the EL34 sick bay with a dead channel. I am building a Nelson Pass designed Triode Tube buffer, but the tube is the Korg NuTube -- a mini low voltage triode that is very different. Check it out at First Watt or DIY audio or here: https://www.audioxpress.com/article/...org-nutube-6p1. Embrace the audio diversity!
    Reviews say microphonics are terrible and its gain is low, but it's about time the Korg NuTube started gaining ground with the diy community.

    I may still build one of those little Tube Depot amps. Maybe a pair of the monoblocks to sit on top of little TM speakers. Active speakers lol.
    I just took a quick look on Ebay for original ST-70's. After seeing what current pricing is, I agree. I think I only paid about $200 when I got mine, but complete amps are hovering north of $700 now. For that price, I'd want new stuff that I know works.

    I heard my Old Skool B9s through a 35 WPC push-pull tube amp in an outdoor setting a few weeks ago. I've never heard them sound so good, everybody was pretty amazed. Would a nice SS amp sound just as good, I don't know but a tube amp is definitely on my radar.
