Manufacturers often specify a recommended loading value or range that best matches their cartridge. This is the optimal impedance that should electrically load the cartridge. If an impedance of that value is simply added in parallel to the phonostage input circuitry, sub-optimal result are often obtained. The main reason is that the actual loading seen by the cartridge is the combination of the impedance of the cable, the input impedance of the phono stage input and the variable loading that phono stage manufacturers usually provide. Moreover, some cartridge/tonearm pairs can also exhibit resonance in the audio band, which can be seen as accidents (peaks or dips) in the frequency response. Such ringing can also be slightly tamed by proper cartridge electrical loading
(...) And add them to the list of manufacturers who really understand what loading is all about:
Congrats on the CH L1! It's been revelatory, an end of the road piece for me. In a way, using the C1/X1 alone for half a year was instructive because the C1 has a way of illuminating musical themes, imparting coherency that makes classical music so rewarding. The CH L1 added width and depth to massed strings and more timbral accuracy and fluidity across the board. What wires are being used with the L1? Is CH M1 in the cards? Hopefully my upcoming NYC visit will address these areas; and of course the full FMA system/Zellaton statements are crying out for an audition.
I made my fourth visit to AudioArts this week and thought I would share the experience. This time we heard the Zellaton Stage, ASR Integrated with battery supply, Thoress tube phono stage, updated Garrard 301/Schroeder/Jan Alerts turntable. The only constants are the Zellaton Stage speakers. I've heard them on all four visits. Everything else was a first for me. This session was all analog. This set-up produced outstanding results. We started with Johnny Hartman's "The Voice That Is", "Sunrise, Sunset". Johnny Hartman's voice was absolutely beautiful; full, rich, lifelike. Soundstage depth was excellent too. Next we listened to a few tracks from Charlie Byrd and Laurindo Almeida. The tone of both guitars was realistic with a perfect blend of highs/mid/bass. Bite of the strings was reproduced. Again excellent soundstage depth and placement of the two guitars. The conclusions I drew were: the Zellaton Stage speakers are outstanding paired with a variety of electronics since this was the third set of electronics I've heard with them and each time I was impressed with the results. The turntable/arm/cartridge and phono stage produce a warm rich presentation. Good detail too. Finally, the ASR integrated performs admirably when compared to CH Precision and FM Acoustics. I thought the overall tonal balance to be more rich, rounded, less detailed than the CH Precision and FM Acoustics. I preferred the CH Precision but could easily understand how someone could pick the ASR. Nice combination all the way around. The better comparison is the FM Acoustics amp/pre/phono, Sperling turntable, Fuuga combination. It was more lifelike, dynamic as I recall from three visits ago. Clearly the better analog set-up. I did not ask but assume the FM/Sperling/Fuuga is quite a bit more expensive.
Asking the above question because considering pairing the ASR with my Zellaton Emotions.
