Vinyl recordings - best methods
hi there again, dgarretson, and others, I am in for my yearly 'best of' vinyl recordings. For now I will use the DA-3000 as is - it has served me really well - but maybe I could upgrade it in the fall. What are the DA-3000 mods that really make a ... 
Why are my woofers pumping?
My short summary, so far. Vinyl rips from my main rig, made on my DSD recorders, played back at my modest cottage system, are able to reproduce subsonic pumping. When I play digital including advanced digital at the cottage system - SACD - there i... 
Why are my woofers pumping?
Atmasphere - thanks for hanging on, what would A-gon do without such good advisors. Today I received the millimeter version tool that should help tighten the housing of the Hanss bearing. When I get my friend over we will turn the whole heavy play... 
Why are my woofers pumping?
Back home testing woofer pumping on Pink Floyd: The Wall, the dreaded thing happens, my neighbour (house is vertically divided) rings my door bell and asks me to turn it down PLEASE. It happened after I played the "shotgun" drum/bass effects in th... 
How much do I need to spend to get a preamp that sounds better than no preamp?
Back to the original q - I had to pay ca 4 k dollars  to get a preamp better than the direct input from my Aesthetix Io phono stage. Einstein The tube mk 2. Bought second hand. Have not looked back. 
Beware the audio guru
Cleeds - good question - how to diminish the «I know better than you» guru factor'. The «collective» power of Audiogon is what makes it interesting for me. I wish the proportion of people who actually listen before judging would be better, but all... 
Why are my woofers pumping?
Back testing my cottage system playing SACDs. System is good enough to show the considerable step up from CD sound. Almost as good as my vinyl rips. And like before - with digital sources i see no pumping.  
Why are my woofers pumping?
Conclusion so far - maybe, just, live with it, until the next cart change. Facts: - Pumping carried over to the secondary system - clearly not amp or speaker dependent (digital LP recordings). - Arm bearing, turntable, drive, belts etc - no indica... 
Why are my woofers pumping?
Testing DSD recordings made by the same cart-arm combo on a different player, the VPI HW19, some years ago. Not quite the same, since the recording was made with the Lyra titan i cart, not the Atlas. Yet they have the same compliance and should be... 
Why are my woofers pumping?
Yes - or simply, the vinyl groove noise... 
Why are my woofers pumping?
Back home, some more testing on main system:Audiotomb suggested an arm bearing test. I set the SME V so that the arm floats, zero weight and zero anti-skate, can I lift it with a light feather? Yes. Movement is vertical, not slanted? Yes. Can I dr... 
Why are my woofers pumping?
Ct0517 you are right - i’ve installed two beams in the cellar under the rack - I hammered them into place, a horizontal plank on top of each - it makes a lot of difference - i can jump in front of the player without mistracking. This, and separate... 
Why are my woofers pumping?
I have been thinking: the main culprit is the cart-arm combo's low resonance. But is it? Much is in the blue, since the HFN test record is known to be somewhat problematical (e g dont use it to set antiskating), calculators may be crude and we don... 
Why are my woofers pumping?
It seems that to use the single ended Kab filter from the balanced outputs of my phono stage (having tested that these sound better than the single ended outputs) I will also need a converter box. It becomes complicated.  If KAB was next door of c... 
Why are my woofers pumping?
Update: situation in the system at the cottage seems like with the main system at home. Vinyl records including DSD recordings of these made by the same cart-arm-phono-preamp in the main system, create pumping, more or less. Its not just Meddle, b...
