Simplest Linear PSU?
In my understanding, source components for obvious reasons require the most silent power supplies. Absolutely. I go nuts getting really quiet power for moving coil RIAA phono stages. Think about the impact of even a small amount of noise on som... 
Simplest Linear PSU?
@clustrocasual So many things to unpack. Look i dont really care what you believe, but i want you to understand, and every reply proves more and more that you are not following my points. 1. I don’t like the sound of SMD components, so seek t... 
Simplest Linear PSU?
@lewm  Regulation, if perfect brings noise to zero.  Nothing in this world is perfect.  Most regulators generate high frequency noise which can have nasty audible effects (likely beats, but it really doesn't matter - they do). I agree that overal... 
Simplest Linear PSU?
I should add that the link above describes what appear to be very well thought out supplies, at a not-insane price considering what's inside them.  I pay little attention to the stand alone LPS market since i design LPSes for use within products. ... 
Simplest Linear PSU?
I am a fan of small chokes to eliminate the HF noise generated by most series regulators.   
Simplest Linear PSU?
Transformer, Bridge Rectifier and filter caps..... yes, that's the simplest but likely not the best.  For constant current draw stuff, multiple filter stages can be very very good, and sound remarkably right. but for anything requiring specific... 
Simplest Linear PSU?
Guys - the amazing level of confusion continues, post after post. The OP asked about power supplies that were made with SMDs. Maybe he mistyped, maybe he has no idea what he’s typing, but he did. SMDs are surface mount devices. Note this means th... 
Simplest Linear PSU?
SMD, not SMP = Surface Mount Devices THT means through-hole devices often the same devices, different leads. Which is why the criticism is misplaced, IMO. There are bad components of all types. And also good ones.   On the topic of SMPS (switc... 
Simplest Linear PSU?
@clustrocasual Obviously buy what you like, and what makes you comfortable.  But the purpose of these sites is to share info, and I'm trying to counter what i see as knee-jerk reactions to modern technology.  Some SMD IS bad.  But some can be ve... 
So, I listened to a $1Million Dollar System
Well, setup is a big part of any system and obviously they cant do that very well "on the road".  I'd also mention that good systems make bad recordings sound as they should (or maybe the word is "as they do").... bad. But what you recount is dif... 
What should be mandatory in every professional published review-
@soix  Just in case it was not clear,  no disrespect at all. No ding on "professionalism". but folks were talking as if they coudl define high end reviewers like plumbers, lawyers or economists.  Heck, mybe behind screen names we know each other,... 
What should be mandatory in every professional published review-
here's the issue.  very few of the reviewers you know make their living reviewing. They are published, yes.  Might even get a few bucks for a piece. but they have real jobs. Its a hobby  
What should be mandatory in every professional published review-
One major practical issue is that ow the reviewer needs to be familiar with the previous unit.  Or, now his/her work is at least doubled, to in effect, review two products.  In the end, most will not really want that review.  They want to hear abo... 
FUSE Question...Very Confused Please Help !
what they said.  
DACs that do well without a preamp
@mitch2 Some quick answers: 1. No i have not listened to the unit you mention, but i have experimented with it myself. It does have one major limit- which you allude to below. The contorl must be very noise free 2. Paul’s quote is irrelevant f...
