Power Cords
Sweet dreams, EBM... Do not let us obsessive audiofools disturb you *Grins!*Meantime, I have been using a full loom of Cardas cables for several months.... The newest Clear Beyond XL power cords on Rowland M925 monos, M525 bridged, and Esoteric X-... 
No-one talks about Rowlands anymore
Hello Jimmy, those M7 golden beauties might outlast  usthe both of ... Not bad at all for amps that were manufactured somewhere in the late 1980s.... by a company that "no one talks about any more". The only issue they ever had during the wonderfu... 
Absolute top tier DAC for standard res Redbook CD
"@david_ten - If you like NOS PCM DAC designs (no DSD), I suggest you check out the Metrum Acoustics Adagio which is their top of the line. It incorporatesa unique volume control implementation which varies the operating voltage of the DAC rather ... 
How are you hearing no difference?
Listening with just your ears does eliminate the effect of psychoacoustics quite plenty if you are totally blind, and you ask the in-store consultant not to tell you which one of the several amps, or preamps, or players, or cables, etc...   in the... 
How are you hearing no difference?
Really funny, I do nothing but blind listening, and have no problem hearing differences between components.... Yep, I listen only with my ears *Grins!*G. 
Beware of new material claims - the case of graphene
Weaponize graphene? In the high end audio industry? *Vigorously Scratching Head!*G. 
Beware of new material claims - the case of graphene
Oh... Like in "this here graphite thingie makes 'em 'lectrons go real goodly"?!Yeah, may be, but the word superconductor has a very precise meaning in physics.... And misuse of "superconductor" "graphene", and other such neo-trending words in mark... 
Beware of new material claims - the case of graphene
There is no such thing as a room-temperature superconductor.... As far as I know, the highest temperature superconductors created this far require to be cooled at the temperature of liquid Nitrogen... Beware of extraordinary claims!G.  
Beware of new material claims - the case of graphene
Graphene is not a mono-molecule layer of carbon... It is instead a mono-atomic layer of carbon, arranged in a hexagonal latice... There are no molecules per se in graphene, but the entire graphene sheet or micro-sheet, be it bound to a substrate o... 
Beware of new material claims - the case of graphene
Hello Geoff, the problem of using graphene as a material for uber-strong composits is -- at least for the moment -- the ubercost and low feasibility of creating long fibers in bulk/industrial quantities.... Typically, structural composites are for... 
Beware of new material claims - the case of graphene
eYes, a mono atomic layer of graphene is stronger than a monoatomic layer of Iron doped with carbon... And so is a thread of a spiderweb.... However, we go through spiderwebs without ever feeling them.Besides, how does this superior tensil strengt... 
Beware of new material claims - the case of graphene
It's no so much how he builds some parts of his cables using graphene, but why.... And is he using proper graphene two-dimensional crystal latice, or much more readily available and inexpensive bulk graphite powder instead? Graphene is constituted... 
No-one talks about Rowlands anymore
Hello YYZ, @Alsteward might be able to tell us a bit about the sound of Daemon, as he has heard it at Expona.... I have not heard of direct comparisons of M535 with M825 or M925. However, all reports are that M535 is stunningly good for its $5900 ... 
Experiencing Rowland M925 4-chassis reference amps
Thank you so much @Alstewart... You summerized my own M925 experience to a T!The reason why M925 monos never get really hot to the touch is that they have an efficiency of approximately 93%.Ther power is approximately 430W into 4 Ohms, reaching 85...

Buon giorno Mike, I left Italy some 40 years ago, and live on the US East Coast.I am very much looking forward to enjoying listening to your upcoming  test of the Rowland M535 amps in bridged mode.Meantime, so that other followers of this thread h...
