The Science of Cables
I have heard subtle differences between how different speaker cables sound in an A-B demonstration at an audio club and the difference was above a threshold of placebo effect. Interconnect cables can sound different if capacitance is not accounted... 
A comparison between two DACs, one R-2R, the other ES 9038-based.
More than 10 years ago, when I could afford it, I purchased an MSB Platinum with upgraded R2R ladders, one in each channel, upsmpling to 384,  and a buffer to eliminate jitter. It sounds very good. I later got an Oppo universal NuForce player for ... 
New Magneplanar Bass Panel DWM
I live in a small house with a small listening area sectioned off the circular shape of the floor in my round house. I recently connected Magnepan 0.7s to my system. The room is not big enough for larger speakers, even if I could afford them. Acco... 
What are the best speakers you have ever owned and why?
I have to go with richopp69. While I remember DQ-10s sounding clear years ago, nothing, not even $50,000 speakers come close to Magnepans. 0.7s are my favorites because they are simple two way speakers and I do not trust pure ribbon tweeters becau... 
What area or country do you live in ?
Houston, Delaware living in a Futuro house since 1977 and this is where I will stay till the day I die.I have had many sound systems and home theater for watching opera.I finally settled for Magnepan speakers driven by 833-A triodes (It takes thes... 
Will a MC phono preamp overload and distort with a higher output MC cartridge?
Thank you. I am going to try the phono preamp. 
If you love SET amplifiers, boy do I have speaker for you.
If I had not fallen in live with the 833-A SET and Magnepan speakers I would want to try this design. The NSMT is a very attractive looking speaker, not only at modest price but ideal for inexpensive to build yourself small SET amps. They draw les... 
How do you know what a good speaker is?
I think Magnepan and Martin-Logan engineers who eschew boxes and simplify the crossover to first order: a capacitor to the tweeter and a coil to the mid-bass regard the very complicated crossovers, notch filters that attempt to tame the wild varia... 
Center Channel with Magnepan .7: Magnepan mmg-c vs Kilpsch
I think I will go with Magnepan for the center  channel. Thank you. 
Speaker recommendation for Home Theater
If you liked Magnepan, the older Magnepan speakers were constructed with wires cemented to the Mylar film and the cement breaks down over the years causing them to buzz. While it is possible to re-cement the wires, the newer Magnepans changed from... 
Sound Quality of red book CDs vs.streaming
Just for the hell of it I looked up the prices of downloads and is it just my imagination or are some downloads just as expensive as buying a CD? Music servers are so expensive and a clocking buffer in a good DAC should eliminate any difference in... 
Trying Magnepans, need advice
I am about to take delivery on a pair of Magnepan 0.7s. I had been using SETs with the 45 which is not powerful enough for their 86 db sensitivity so I rebuilt my amplifiers to let the 45s drive the grids, through an innerstage step-down transform... 
What amps should I audition?
Consider an 833-A SET run at 1000 Volts through a Hammond 1642SE output transformer. At 1000 Volts it will draw about 140 ma which is just right for that triode transformer configuration with the grid bias at ground potential to make the circuit s... 
Tube-amp for Magnepan?
I am considering connecting a pair of MMGi's to the 4 Ohm outputs of a pair of Hammond 1642SE output transformers wired up with the 833-A radio station triode running on only 1000 Volts. Using older speakers this draws 120 ma plate current. Steve ... 
What do you LIKE BEST about your current audio system?
I like what the 833-A triodes do for the bass response of my woofers. My 833-A SET amplifiers are homemade because I could never afford the few commercially made ones available. I run it on 1000 Volts with interstage transformer coupling (Hammond ...
