| 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... | |
| Why are my woofers pumping? Audiotomb - very interesting. I think my arm floats fine but will check when i get home. The HFN record lateral test shows very visible and sonic resonance ca 7hz while the vertical test is much less obvious (the test tone warbles a bit between ca... | |
| Why are my woofers pumping? I am mystified. Why do i see woofer pumping playing Echoes on my small cottage system which is 6db down at 42hz and probably not audible below ca 38hz? All hail to DSD? I play a rip / recording of the same original vinyl that gives pumping in the ... | |
| Why are my woofers pumping? I notice that Pink Floyd Echoes recorded from the LP on my system pumps the woofers also on my cottage system! | |
| Why are my woofers pumping? Thanks Atmasphere - yes the low reach of the amps in combo with the speakers may play a role. But with the Triplanar you dont have the problem. Do you know the resonance of your arm cart combo?Lathes - low frequency - ok - but if it happens betwe... |
