Do the tariffs affect the used markets as well? I'm thinking yes but not sure. @dz13    Yes. Think of it in terms of shortages. This will push the used market up as new prices go up as well. Its a manufactured inflation.  We make our boards he... 
Is there usually a dramatic difference between $5k and $10k cartridges ?
how do you choose cartridge that your arm will track perfectly ? @inna Good tonearms are a trick! You'll want to use a calculator like this one. A good arm will have absolutely no slop between the cartridge mount and the base of the arm. Its... 
Is there usually a dramatic difference between $5k and $10k cartridges ?
@inna @rauliruegas  and @lewm both make good points. I have two more to offer that are in the same vein: 1) the ability of the arm to properly track the cartridge is far more important than what cartridge you have. 2) there is something called t... 
Turntables currently considered top of the range. Do you know what they are ?
Yeah, that's interesting what tube power supply did there. I have a hypothesis - tubes are just superior devices, whatever you do with them, if you know what you do. @inna knowing what to do with the devices is far more important than what devi... 
Calculation verification please
I always thought loading was to dampen the stylus against any 'ringing' which may occur... @quincy Nope! Especially with LOMC cartridges, which have a very high 'Q' factor in their coils (so as to minimize mass) the result is that the peak I me... 
From Audio Note AN/J-D to where?
@apollinaire You might consider the DeVore Fidelity O96 which is very easy to drive with lower powered tube amps but has wider bandwidth.

Your journey with lower-watt tube amps -- Can a kit be good enough?
@hilde45 That link doesn't seem to work.  
Your journey with lower-watt tube amps -- Can a kit be good enough?
@hilde45 Excellent! If you change a component in your system and then you run into a buzz, this can be one of the causes. But in your case its not happening so no worries  
Calculation verification please
@sksos1 The cartridge won't care about the 375 Ohm load. It won't care about 30 Ohms either. Loads like that are never for the cartridge's benefit; they are to eliminate RFI (Radio Frequency Interference) that LOMC cartridges tend to generate. Th...

@lynn_olson +1 The tariffs will be doing no-one any good at all; just shortages, inflation and ill-will.  
Your journey with lower-watt tube amps -- Can a kit be good enough?
@hilde45 Nice to hear you hare having success! I prefer the JJ EL84s. You can get matched pairs at CE Distribution They have a Psvane tube that looks interesting too. If the power cord is grounded, sometimes you can run into a buzz problem (grou... 
More on XLR vs RCA considerations?
I've never heard of a single ended triode preamp, but maybe that's just something else I've never known about until now?  @immatthewj Most tube preamps are single-ended and triode. Its the rare one that isn't! Since my preamp and amp are sing... 
Cleaning amp/preamp
If you have a board contaminated with oil a car wash (the kind where you use a pressure wash and do the cleaning yourself) can be a good move. I've had to do this a couple of times when customers put weird 'contact enhancers' on their tube sockets... 
Can you do anything to make power tubes last longer ?
If you’re talking about the US, you are mistaken @atmasphere. Nominal voltage in the US is 120VAC ±5 percent, so anything between 114VAC and 126VAC is normal. That is established by ANSI C84.1 standard. @cleeds I stand corrected.  However if t...
