Quote: Thanks so much Jason!!   I wanted to try and test and make sure I didn't waste your time.  Don't for a moment think I am not a happy customer, I own a Lyr too. my unit is B080137 maybe number 137?     By the way it does sound awesome!

Quote: I am trying to gather as much data as I can so that we can fix the issue. I am totally committed to providing something not just venting. Once I have a complete roundup and test against Linux and Windows systems I expect to reach out.

Modi problems, good news, workaround without reboot.   Report:  The Modi sounds great for a certain period of time. I have tested the device from USB powered hubs, directly to  two different Macbooks and I definitely have an ISSUE.   Background: I am far from a MacOSX expert but I...

Just got in some Japanese 12AT7 tubes,  lucky me included in the lot were 2 Marconi super-rare made in Japan tubes.   And i found some GEC B309s,  i guess we should have a flood of tube reviews soon!

Quote: Jimmy Page and The Black Crowes Live is excellent sounding.

Quote: will you be modding ksc75s for people?

Quote: you rock, all new as of yesterday.  you must be pretty amp'd  (ignore bad pun)

Quote:   Are you sure it isn't the headphone cables microphonics and not necessarily the tube? Did you try and switch the tube to the other spot and replicate findings?

Quote:   If you just got the tubes, they do need some burn in,  secondly it takes a while for the Lyr to warm up.   From my testing, I do think the 7v Tubes PCC88 7dj8, seem to have more "air" and "separation", these are usually a steal since very few designs call for a 6dj7...

Got some Rare GEC and OSRAM B309/A2900 tubes for 12AT7 guys to try. :)   And barring disaster a HP 339a Distortion analyzer, for some testin. http://cp.literature.agilent.com/litweb/pdf/00339-90001.pdf

Quote:   So i just switched mine back in.  They do sound nice and smooth. Great for jazz and ambient.

Quote: Try a LOD cable, it makes enough of a difference with line level out to drive T1 awesomely.

Quote:     I believe this correlates with the Freq Response graph Dan put up. There is some dip 40-85Hz range then a quick rise.  I might be confused.   http://www.mrspeakers.com/image/data/mrspeakers/MD%20frequency.png

Quote: I would totally agree on that analysis of the two tubes.  Definitely the Tesla has more bass tonality.   For what it is worth, I have the Russian set of tubes from Schiit and they have almost no bass response very airy.

I have the JAN Philips 6922s, but i think the BEST bang for the buck is   Tesla ECC88 6DJ8 1960s NOS (NOT JJ) - M. Pairs MINT NOS - Rožnov Prod   Should be 30 bucks for a matched pair  I believe they sound better than the JAN Philips

My experience/tests with Maddogs.   You do not NEED an amp.....  However, for the most part, with the better amping you provide there is a scalar relationship with quality on the MDs   Amp 1: Lyr, this is a great pairing, but note that the Lyr is a great tube rolling device, there is...

I can bring my HP Distortion Analyzer/Oscilator as well. this is a neat little tool.

I can bring my Maddogs and a Project Sunrise II also a Lyr if no one brings one to try tubes.

get the MDs and a amplifier. :)

Built my PSII   Here are my findings.  I have tried both 6 volts and a 12 volt tube.   6v: Telefunken 7dj8:  Echo or Reverb like bass, runs cooler than a 6dj8.   JAN Philips 6922:  Good all around, better bass than the Gees Tesla 1960s 6DJ8: Very nice highly recommended at 30-40...

Another finding, when you do itunes cloud download it seems sometimes files are saved with a .m4p extension.  These items do not seem to play with Bitperfect.   Unless....you rename them to .m4a,  i changed the extensions and nothing really broke. and now songs that were not being played...

lyr is outstanding with t50rp i also recommend a Project Sunrise II, it works well.

Just build my Sunrise II ,  this thing with a nice 12v tube kicks. I feel depending on tubes you  have in the Lyr (sub 200$ tubes) the Sunrise is just as good and drives my T50rp Maddogs beautifully.

Don't get scared away by a DAC, that isn't a requirement for anything at all.   Basically what we are all saying is that,  there is another level of dynamics that can be achieved with Maddogs (and likely orthos in general), these are for want of a better world "scalable" the more you...

the mds respond to very well to EQ provided you have the power to drive them.
