Schiit Lyr - The tube rolling thread - Page 481  

post #7201 of 8735

Just a quick review.

 

For the people that will be having a set of my adaptors, the tubes i recommend to use first are the Tungsram E80CC

 

They are my favourites of all the tubes i've tried so far, and can be found quite cheap for a pair on ebay, although there aren't many pairs available at the moment.

http://www.ebay.co.uk/sch/i.html?_sacat=0&_from=R40&_nkw=tungsram+e80cc&LH_PrefLoc=2

 

The sound seems very neutral, bass and mids are in good proportion, if anything i would say the mids have slightly more presence than the bass, treble is lovely and smooth and airy.

Soundstage isn't their strongest point, but it doesn't let them down, seems to have just the right amount of space, deffinitely not closed in.

 

They are not ultra detailed, i find myself switching back and forth between my D1 and my Lyr with these tubes in to compare them, D1 seems very precise and cold sounding, these tubes present a slight fuzzyness, like a kind of lazyness to the sound, they are still a detailed tube, but softly so, quite hard to describe. I think this is due to running them out of spec, they are described as ultra detailed by many people that have used them, but they aren't using them in the same way that we are.

 

They are a very quiet tube, zero microphonics, that is probably thanks to the individually boxed anodes that is a characteristic of this family of tubes. I can only hear a low humming sound when i plug really sensitive headphones into my Lyr (Yes i had a mad moment and plugged in the UM Miracles) But anything else that requires a good amount of juice (Planars, etc) it is a pitch black, quiet background.

 

I think for the price, this is one that is well worth having in the collection.

 

Disclaimer: DO NOT plug E80CC straight into your Lyr, they are NOT pin compatible and need an adaptor (pictured) to make them work.

New toy on the way  biggrin.gif ...as if my audio gear hobby hasn't burned enough holes in my wallet already.

Along with a set of 4 9AJ adapters.   

 

It was either this or the Tube Imp, but I like that it does 4 at once, tests noise and has audio outputs for an actual listening test.

I've been looking at the Tube Imp, would be nice to have one to see if the ebay sellers really are matching their tubes properly.

It's good to remember that we're dealing with some very old devices (if we're lucky) and that sometimes things can fail. Those glass envelopes are exposed to heat a lot, so it's not all that unusual to hear of tubes failing like that.

 

I'm looking forward to hearing how you like the replacement tube.

 

I think you originally posted the link to the ebay listing so I figured I would be in good hands.

 

I'm really not surprised to hear that tubes fail relatively commonly considering the age. Heck most of the stuff made these days doesn't last more than 5 minutes! I have to say that I regularly have a 'wow' moment when I remember that the tubes I have plugged in were made around the time the Beatles were still together, before man landed on the moon etc. 50 year old components in a modern bit of kit - mad really eek.gif

 

I did really like the BB's from the brief (25 hours or so) time I spent with them, so will be glad to get a working pair again. Pretty happy with the Brimar's I had to fall back on though.

 

Even though I got a replacement BB sceleratus still went ahead and sent me the pair of Lorenz PCC88's he'd offered if I got stuck. Incredibly generous of him and I'm really looking forward to trying them out!

I did wonder how much these things cost. Not cheap but if you do a lot of tube rolling, buying or selling then I can imagine it will be money well spent.

That's something that struck me when looking at a lot of ebay listings. You're never sure if they've done the matching using a tester, by ear, coin flip etc. 

 

 

I had a bit of a holy schiit moment earlier when I spotted this listing in trading: http://www.head-fi.org/t/663708/matched-pairs-or-quads-of-nos-siemens-halske-cca-e88cc-6dj8-silver-shield-1960s-superb-condition

 

60 pairs and judging by the pics they look as good as the day they were made.....wow! Well out of my price range but maybe one day.

I got a pair of socket savers today, and if I didn't know any better my Orange Globes now have more detail!.

Speaking of tester and analyzers.....

 

Valve analyzer rev 1 wasn't feasible.  It used an autotransformer with mains voltage in the circuit.  Although I got it working, it was too dangerous.

 

Rev 2 components are already arriving.  I will implement test points across gird/cathode/plate for integration with a curve tracer, oscilloscope and DMM, as well as having dedicated panel meters.   Easily another 90 days to proto-board, simulate, finish and etch the PCB.  I have some small daughter boards for voltage regulation that have SMD components.  I going to give soldering them a try tomorrow.  It will be a challenge with my shaky hands.

 

All the components are rated for high wattage and 1% tolerance or better.  I am also implementing EMI filtering/chokes on all the leads.

Here's the old panel design, it will change considerably.

I have faith!  It's gonna be awesome!

Can't afford a Bifrost right now, and was considering te Modi. Do you guys think this is a good idea? Maybe buy the Bifrost a year or so from now.


Edit: I should state that this is to pair with my Lyr and Hd 650's.

Do you need to warm up tubes before use, if so for how long

I'm thinking the very same thing and would love to know the answer. I've just bought the LYR to drive my HD650s and I'm wondering if the modi would be an adequate stand in, until I can afford the Bifrost?

Use the odac does a real good job

About 20 minutes warm up is plenty for most tubes. I've found that some others like ECC85 require about an hour or more.

+1

 

I have the Epiphany Acoustics version (E-DAC as they like to call it) and am very pleased with it when using my Lyr with either my Denon D2000s or HD600s. For me it's definitely good enough to tide me over until I can afford to upgrade.

 

The thing that swayed me towards the ODAC over the Modi is that it is powered purely by USB, which is great if sockets are at a premium.

Amperex Holland 6DJ8 PQ shield (Tekronix Checked) turned up today.

 

 

 

 

 

Oh.. My.. Word....

 

I don't think the words have been invented yet to describe the sound, they are THAT good.

 

Can't believe i got these for only £35 posted.
