Can I run Siemens Blue Glass 6Ak5 or Sylvania tubes as the driver tubes in this hybrid headphone amp? They were in a L.D. MK2 originally?

Yes,you can run Siemens Blue Glass 6Ak5 or Sylvania tubes as the driver tubes in this hybrid headphone amp.

I upgraded to western electric 408a I do not know about the other tubes wish I did.

I use the Voshkod 6ZH1P-EV in mine and I highly recommend them. You can also use 5654 tube or 6AK5-W tube types. I think you'll be fine. The Chinese tubes that come with them really do suck.

6Ak5 tubes will work with the jumpers (J1 and J2) set per the manual. Just remember to power off for 10 minutes prior to moving the jumpers to properly drain the caps. Send an E-mail to the folks who import the little dot amps for more info.

The best thing to do is to contact Siemens by email. I did once and they did respond. You should mention brand name and model numbers of your headsets.

This little guy really shines as a headphone amp, but does well with speakers too. In your case, I'd be a bit worried about clipping since it's rated at about 17 watts @ 8ohm. No experience with lower impedances. If you're not set on a hybrid tube design, check out some of the dedicated solid state 2 channel stereo amps by Denon or Onkyo. My Onkyo does wonders with digital files with its built-in Wolfson DAC.

It's a passive device. Not sure why you would need a driver. Before getting the Muse, I used a DAC made by Chord, no driver required. Don't recall just why I switched to the Muse, but it does the job and I'm still using it.. Output from the Muse goes to the digital coaxial input on my receiver. Plug and play, nothing else required.

Anyone try running the output through the Fx Loop Send, increasing gain and lowering the Volume(so the speaker isn't heard)?But if this works you'll loose the Power tube phase. I'm using Blackstar Ht Metal's Emulated Output for this purpose.

The preamp section is digital (DSP), and the output section is tube (2-6V6 w/ 12ax7 as a phase inverter). As such, the amp is a hybrid.

They will work but a good headphone amp really does help the finish on loud passages. Try the Schiit Magni for $99. . .great quality and great price.

There is a very extensive thread on this unit at head-fi. There is a FAC on the first page that has a lot of different tubes tried by the owners & their impressions of them. Most were an improvement over the stock tube.

I know this review is from 2013, but I want to say I am using the same pair of headphones with the JDS Labs O2 Headphone amp and standalone ODAC and it has made a major increase in listening quality for them. The Amp alone at least doubles the quality, whereas the DAC will clean it up for you.

I have had excellent results with the Bottlehead Crack and Beta22. For the latter, I wanted a very transparent amp to match the headphones.

Sorry to disagree with Blake, but I own about every travel amp including Roland minicube, Mustang beats it hands down. Same size, much better sound, cheaper... those 24 presets and good twin reverb sound are bees knees. Haven't dropped like micro cube however. Cube was great in it's day, but things have improved

I used them with this tube amp (http://www.amazon.com/GemTune-Class--Tube-Amplifier-EL34-B/dp/B00DRUY6EG/ref=sr_1_2?s=electronics&ie;=UTF8&qid;=1449284595&s;r=1-2-spons&keywords;=tube+amplifier&psc;=1) that only has 10 watts per channel, granted, a bit more power than you are asking about. It filled a medium sized room well. Say 15x20 feet. But as others said, it won't rattle he windows. You could also give this inexpensive amp a try (http://www.amazon.com/dp/B00F0H8TOC?psc=1), the sound is surprisingly good.

I'm probably not the best person to answer your question because I drive my headphones with one of two tube driven amps, but I'll help. The Emotiva headphone amp/DAC will drive almost any headphone easily. The Fiio E7 may or may not be adequate for the 300ohm HD600s. Check the Fiio website for specs and look for a suitable range of headphone impedances (if listed) for this amp/DAC. Also, check head-fi.org or innerfidelity.com for more info on headphones amps/DACs where you can find reviews. Sometimes an amp/DAC will recommend a headphone impedance range and a reviewer will have a very positive review of headphones NOT within that range - YMMV. Good Luck.

Yes, the 12ax7 in a single package replaced two 6av6. So, the tube can power both channels. One can also experiment with tubes from other vendors and achieve different tonal responses. Each vendor has different characteristics they market (guitar amps, receivers, preamps, etc.)

That is what I am using them for, because I cant blast in my apartment on the pair of M & K monitors through a Dynaco tube 70w amp, all rewired in Monster cable!The advantage of these cans is they go so low and flat, you know exactly how much low end you're printing, and same with the highs, without treble peak areas like any Sony or Sennheiser, you know just how bright you are printing. Yes in all fairness you can mix on them, have funBobby

sorry I'm not to tech savvy. I had a friend help and I didn't know much of what was going on. I do have a separate amp, which is an inuke nu1000sp, made by a behringer. I have 3 total, 1 each on three chairs. they do work really good, especially compared to the higher price ones. if I can find more info I will let you know.

THERE ARE NO HI POWER BUDGET TUBE AMPS THAT WILL PROPERLY DRIVE THESE WONDERFUL SPEAKERS. That leaves you with two choices, buy a tube amp kit like the ST120 dynaco clone or purchase a solid state amp. You need at least 60 tube watts for properly driving these speakers.
