Bad recordings and high end audio
Hi @millercarbon ,A great post!I'm agreed with you 100%.I lot of records that sounded bad become much more listenable and musical with my system upgrades and tweaks.Beside stereo records and CDs, I have a number of CDs with 78RPM remastering of ol... 
Super tweeter for FullRange Driver
I don’t understand why most people do 1st order crossover for super tweeters.The only answer that comes to my mind - the 3rd, 4th order is too difficult to implement for average audiophile.My experience shows a huge advantage of 4th order crossove...

3 New UBER Decks - Is this Turntable's SwanSong? 🦢
Most of the best quality records (classical and jazz) were recordedfrom 1956 to 1964.After that transistor equipment and Dolby started used in studios that caused significant sound quality drop.

EMT DD turntable like EMT950 and EMT948 are in the same league as best vintage japanese DD turntables.Actually, many EMT collectors (especially classical music lovers) prefer 950 over 927 and 930.One my friend prefere EMT948 and Yamaha GT2000 over...

Still happily using vintage gear?
I have been using Altec 604E speakers (made around 1965) since 2005 and EMT 948 turntable (made around 1990) since 2011.All off them are great stuff and very good value for money.EMT turntable is plug and play.Altec 604E sound nice as is. But to g... 
Low-sensitivity speakers — What's special about them?
The problem is if you put more than 20 Watt to your speakers voice coil you will get huge TD.For me it is rule of thumb, if speakers can't be driven by 20 Watt amplifier their compression level cause me fatigue.

Here is a very good article about TD in speakers with examples:https://www.linkedin.com/pulse/power-compression-vs-thermal-distortion-loudspeaker-alexander-wilson/ 
Super tweeter for FullRange Driver
Hi @mozartfan ,I you use 1st order, you will hear your supertweeter in parallel with your speaker 3 octave down crossover frequency.It can cause modulation distortions in upper midrange where our hearing is very sensitive.3rd and 4th order work mu... 
Super tweeter for FullRange Driver
I bought Fostex t90a supertweeters for my Altec 604E 1.5 years ago. Since most people use these tweeters with a 1st order filter, so I used with a 1st order filter. Moreover, it was technically simple. I had quality Audio Note Cu 1uf copacitors an... 
Best sounding resistors
Does anyone compared Z-foil to AN Silver Tantalum resistors as series resistor in L-pad volume control annunciator?What is the difference in sound? 
The sonic rightness of a mono system.
It is more like flat movie/TV vs 3D movie/TV.Flat TV and Mono perception is more easy, laconic for our brain, less redundant information.  
Horn speakers , high efficiency but not “shouty”
Hi @johnk ,How do you compensate a low midrange drop that is typical for all full range drivers?Is any other solution than front horn to support these frequencies?Regards,Alex. 
Whats on your turntable tonight?
