In Reply to: RE: The DL-S1 would be hard to beat I would imagine.. posted by flood2 on February 04, 2016 at 00:37:57
Hi Anthony,
The frequency response chart that came with my DL-S1 used a load of 47k-ohms and went from 1-kHz to 50-kHz. I couldn't find out whether the TRS-1005 was RIAA equalized or a constant velocity sweep. I have a feeling it might be a constant velocity sweep. The TRS-1007 is an RIAA test record with a 20-Hz to 20-kHz sweep.
Best regards,

Hi John
Thanks for sending the scan. Here is the one for my DL304 - they look very similar if not identical at and below 20kHz. The S1 appears to have a slightly greater rise at 30kHz to 50kHz, but it could simply be that the test disc used for mine was worn more.
It is interesting that the measurements for yours were done with a 47k load and mine with a 1k load.
I am wondering if the measurements are being done using a SUT and they are specifying the matching load to achieve ~100ohms? 20:1 in your case and 10:1 in mine?
I think you are probably right about the test being constant velocity - the possible errors that might occur with the equalisation during cutting, not to mention distortion due to the cutting head having to be driven very hard would likely give rather inconsistent results when being used to verify the performance of the cartridge.

These charts tell very little about how a cartridge sounds....just advertising.
Yes,but John and I own the cartridges and compared them to others and find them both technically and sonically excellent. Charts like these go a long way to identifying possible anomalies that might contribute to tonal imbalances. For example the brightness often attributed to cartridges like the AT440ML is due to an engineered emphasis around 10 to 12kHz. You will note that these cartridges have a very slightly reduced output in that range.. As do the Shure cartridges and Stanton.
Anyway, the point was that we were trying to compare the reference load used to establish the performance relative to the specifications.
