Great bass from a linear tracking arm?

I have heard the airtangent on my deck (brinkmann lagrange) - it sounds sublime. However it is limited in the bass even though every thing else is unsurpassable. The bass was the only respect in which the brinkmann arm was better - and the difference was pretty huge.

Sounds like it wasnt setup properly - the brinkmann 10" arm should have very low distortion.

The airtangent not only had less bass but it was vague and lacking in detail solidity extension impact etc compared with the brinkmann arm - and the timing was not that great.

I think my nude brinkmann emt is quite light and that was the cartridge I heard on the AT - it has no body after all. I am guessing it is 6g? What does the zyx universe weigh?

Yes I put the bass issue down to the low pressure pump used and I agree it should come with a better pump. However that is an engineering issue not a setup issue as the arm was set up perfectly as supplied. I am gratified to hear that it does make an improvement however. I am interested in the kuzma as it appears to be a high pressure design. Anyone compared them in the same setup? What pump did these guys use? Were there any other mods?

I thought the CA designs were even more limited when I heard them.

Nope, I was just guessing as it doesnt have a body. It might well weigh a lot more. However I am using the older emt - not the titanium (which replaces some plastic parts with metal) so the titanium could be heavier. Is the zyx really half the weight of the emt?

EMT compliance is 15 micro m/mN

The AT bass was still pretty good - on a par with or better than many pivoted tonearms but nowhere near as good as the brinkmann arm. I would certainly revisit the AT with a higher pressur epump to see what effect that had.

What PSi does the AT pump work at and what would be a better choice at a higher pressure?
