Hello all,

I have a pair of Mad Dog headphones like this guy and I have been set on going SS and upgrade from my Schiit Modi amp. However, curiousity kicks in but I am a complete newbie about tube amps (and tubes in general). My question is not Mad Dog specific as that would seem better placed in that thread, but more about general idea of tube amps..specifically the Schiit Lyr.

I already knew going down the tube amp road would be more expensive than SS, but what is the lifetime on tubes? If I am going to invest in some tubes ($100+), how long do they last considering you use them for 4-5 hours a day? Do the stock tubes that come with the Lyr amp not compete in anyway to these tubes I am seeing on ebay for $2-300?

I have never experienced tube amps.

Hey - great headphone!  I am ordering the new Mad Dog Universal with the improved connectors and the 1/4" single end cable tomorrow!  I should have them in a week.  I needed a semi closed back for when the wife is vacuuming, neighbor mowing the lawn (as you've probably read I like a very quite background for my music).   I'll be able to give you a better perspective on how they osund with the Lyr and various tubes, in a couple of weeks.  I also want to try an ortho HP to compare to my HD800s.  I have read really great things about these bargain HPs (good Mad Dog thread).  Some have said it betters the LCD3 and HE-6s in some ways (especially the latest version with the Alpha pads).  I and others, keep bugging David Mahler to add them to his historic "Battle Of The Flagships (58 Headphones Compared)"review thread.

 

To answer your question on how long tubes last.  The Lyr takes a 6922 or 6dj8 and the many equivalents.  The 6dj8 is rate at approx 7,000hrs the 6922 10,000hrs.  I have had a pair of compatible Voskhod 6n23ps running daily in my integrated amps for 4 years about 8 hrs a day (back ground listening in my office) without issue.  These are known to be particularly hardy tubes.  I've had Amperex and Siemens tubes fail after just a couple of months - so it can vary.

 

Give credit to Schiit for not shipping with the typical generic JJs or Chinese tubes alot of manufacturers use.  They come stock with decent GEs.  One great thing about this amp it really scales well with better tubes, and that is what this thread has been all about.   Folks have been having varying degrees of success from $800 Amperex 6dj8 pinched waists to $20 Voskhod 1990s 6n23ps and everything in between.

 

So the fun/mania of this amp is the ease and flexibility of trying different tubes. 

 

The Lyr can be bought used for around $300 - it's one of audios incredible bargains! (like the Mad Dogs).  I'm selling my $1000 Woo amp and keeping the Lyr.

 

Do your home work and spend a little time reading the last 50 pages or so of this thread.  It would be worth the effort.

 

What source do you have?

Thank you for your reply. Yes, I should and will be doing some more homework on this. My source is a The Schiit Magni (I have the Magni & Modi stack). I use them currently in the lab/office/school but was looking at getting something at home. So the Schiit Lyr or Asgard 2, and the Bitfrost

Good sources!  I hear the Mad Dogs like juice?  I'm thinking they should really shine with the high octane Lyr.

 

That said I have to admit I'm a tube DAC guy myself biggrin.gif

I also love tubes fun. To roll and just have a sweet sound. Many people prefer SS but for me it's tubes
post #8691 of 8735

tektronic orange tubes have been performing really well, although one of mine is a dark orange one, althought mercedesman said they were matched, it's of same year 1972 different week probably close 2 months, it arrived smudged up labels, and after me using duomax dampers X4 on them they scraped off easily almost everything, I was careful about using the dampers, not to position them where there are labeling and printing of those dark orange lettering, but as I was trying to use all 4 of my dampers to see if it helps with anything, I had no choice but to see the labels smudged off, not like it matters because I ain't ever going to sell these anyways and I didn't bother to take a picture before doing such permanent damage because, they weren't looking mint to begin with---, I had to do some cleaning to not let them into the lyr

 

that tube is microphonic. ting and the fades away after i plug in headphone. when using dampers the ting is smaller, but when first opening the lyr there are large amounts of white noise, adjusting the tube carefully takes it away randomly but creates huge noise like when you take off the tube while lyr is on.

 

he has yet to agree to send me the replacement he has without me sending this one back, the reason why he wants a bad one back is beyond me.

NEVER.

Never

Unplug ANYTHING from audio gear when it is powered up.

It will very likely damage a component.

 

The valve is part of the circuit.  Even if were only one pin don't do it.  Same goes for RCA connectors in the rear.

 

The tube has 9 pins  Do you think you are disconnecting them at exactly the same time??   NO  Part of the circuit is energized and part isn't.  "poof"

 

Stop for your own good

http://www.ebay.com/itm/Pair-of-AKG-Studio-Monitor-Headphones-Model-K240-DF-/271240040428?_trksid=p2047675.l2557&ssPageName=STRK%3AMEDWX%3AIT&nma=true&si=o4t08HDgpOSol%252FqsA6jc0Jxp5QQ%253D&orig_cvip=true&rt=nc

 

 

can the k240df be driven properlly(potentially) by the lyr? didn't buyt this one it's got crappy condition, but there is a nother pair for 140 bucks, fair price because it as the msrp, but it was not as mint as mint can go so I am asking the seller for some discount. if you offer less than 100 then it would not be yours just so you know because i am offering 100 to him

 

I don't think money matters though for these k240df, if people say these will shine even with  a 300 dollar amp, then the lyr should be more than enough for them to sing I suppose.

 

currently having more than 15 pairs of cans I care less if I don't get one though. Eventually there would be better conditioned for sale and i can snatch one any time they do, I would buy out immediately if they were sub 100 and real mint condition

 

 

But I do have the k271mkii which was bought when I thought I could stay away from ebay and still get what I want, I am assuming it's not nearly as neutral as the h240df, but it will be similar comparing to all other cans out there

the detail supremacy of k240df is undisputed, probably beats k702 too

interesting how this guy who speak  so furiously about akg gets banned while people on the forums nowadays still agrees with basically what this man said and he did predict right, akg is still going backwards

post #8697 of 8735

the problem is I am definitely not in a stage in life where I enjoy seeking detail like a freak like when I first got the k702. owning the lyr is probably why, it changes you--the sound is less of detail more of rendition

Glad to see I am not the only one on the fence about Upscale Audio. Pretty much no info on their stock, in regards to matching. Sad to hear their customer service is ass. That's one vendor to scratch off.

 

I'm about to pick up a pair of these from Tubedepot:

 

http://tubedepot.com/nos-6dj8-amperex.html

 

So far so good with the Lyr and the stock GE tubes. Room for improvement though (urge to tube roll...rising), but the break-in period is still undergoing.

 

Any thoughts on these?

I've had bad experiences with Tube Depot, and definitely can't recommend them as vendors. Ironically perhaps, I've had great experiences with Upscale Audio. Apparently, others have not which is a shame. Brent Jessee (audiotubes.com) may be your best and safest bet. FWIW, the type of tube I ordered from tube depot is not what they sent. Caveat emptor

p.s. One of the best sounding Amperex tubes for this price- highly recommended:

I had a great day here, we were able to do a comparison with a Schiit Asgard 2 using my own music, DAC and phones and also a shootout to choose the best tubes in my collection for my Lyr. Having the Asgard 2 around as a point of reference helped a lot.
