I keed your help??, re my whole system

Thanks Ramonda
The loading I'm using, are 100 ohms and 150 ohms, you stated that maybe using less loading, but isn't 200-400 ohms is more not less ??, to be honest I don't really know how the loading works?, can you put me on the right track??
Many Thanks for all of the other suggestions

What he means by less loading is to increase the value of the resistance that is terminating (loading) the cartridge.The increase in terminating value is referred to as "less" because the higher value pulls less current from the cartridge.

Also the quality of the loading resistor is something commonly overlooked. I always advise to use common resistors to dial in the value. Then, once you find a value you like, search out a foil resistor (Caddock mk132, Vishay Z-foil...) and use that.

BTW some DL-103 users like to terminate their carts with really high values, like 5k ohm.

I like the DL103r with variable active loading from 300 to 50 ohms.

Moving to the U.S. may be the best use of $$$??? Ha ha!

Thanks Everone, for your input!!
I'm really confused!!
If I was to set the cartridge, at say 100ohms, would it be harsher, then say 200 ohms??. I thought the 100 ohms, would be more smoother?? The makers recommend of the Zu cartridge, is 200 ohms, but on some recordings, sounds very harsh!!
Can someone help??

@daveyonthecoast hey, the JLTi is an excellent phono stage, it can be upgraded by the nanufacturer now to mk5. I use my JLTi with Zu Audio Druid MK5 (actually upgraded mkIV) speakers. Zu speakers are amazing (imo).

The Denon 103 and SPU both share similar sound signature, the only problem is CONICAL TIP. If you ’re looking for extentions on both ends (low and high), and far more accuracy in sound, then Conical tip of your Denon 103 should be avoided! You can have far more articulated and much deeper bass (along with better hights) with more advanced stylus.

For example: The difference between my Ortofon SPU classic GM MKII (spherical) and Ortofon SPU Spirit (elliptical) was huge, but last year i discovered SPU Royal G MKII with REPLICANT 100 stylus profile and this is simply amazing SPU, the best i’ve ever heard, this is a compliment to the stylus profile. The Royal G MKII compete with my FR-7f on Lustre 801 tonearm.

So i think you’d better try a different cartridge on trial (if possible), you can also tweak your Denon with SoundsmithRuby and LineContact stylus. The stylus profile most likely will give you what you’re looking for without any change in the rest of your system! Remember that Conical/Spherical is the cheapest and simpliest oldschool stylus profile and this is why the DL103 (designed in the late 60s) is cheap cartridge.

My second advice is a SUT, no matter that JLTi can handle LOMC without SUT. Adding a SUT may give you what you’re looking for, more slam in the bass. I use Luxman AD8000 with 8020 Silver SUT and JLTi Phono with my FR-7f cartridge, also with SPU Royal G MKII. At least you can try an alternative to active JLTI phono with high gain (what you’re using now) by adding a passive device (a SUT) with JLTi low gain MM input.

As for the JLTi itself i would advice to upgrade the resistors (47k inside the stage and also whatever lower value inside your RCA plugs), but you can do that when you know which loading you like the most. The best sounding resistors are definitely Vishay Naked Foil from Texas Components (USA) and they are different from the cheaper JLTi stock resistors. Vishay Naked Foil is for audio aplications (they are square shape).
