How an audio rack can enhance your amp/pre
Agear, take a look at my post- especially the part about how our Scully lathe was built.Engineers who poo-poo this stuff have to somehow work out how to get past that... 
looking at upgrading my tonearm from a triplanar
- What is the significance of the hardness of a tonearm's bearings? At the tonearm weights involved, that alone wouldn't seem to be important.The hardness is important- the more the bearing has the less sticktion. The size is also important- the s... 
Solid state phono/linestage vs Tubes
The Manley phono stages have a semiconductor input and are not true all-tube phono sections. 
How an audio rack can enhance your amp/pre
Some General Rules: when to use squishies as opposed to points:All audio equipment benefits from damping.Squishies (ex.: Sorbathane) is useful when vibration is affecting the equipment via the shelf on which the equipment sits. It provides isolati... 
Solid state phono/linestage vs Tubes
A tube phono section can be just as quiet as a solid state phono section if a stepup transformer is used.The advantage of a good tube phono section is that you can have a lot less ticks and pops if it is properly designed (this is a function of hi... 
How do you respond to this question?
When I had cats and was playing vinyl they would sit in the listening chair (if I didn't get there first) and look to where the images in the soundstage were coming from. When I put on digital they would leave the room. 
Ringing new NOS tube, is it safe?
Generally speaking, if a tube has problematic microphonics, a tube damper isn't going to help. 
How do you respond to this question?
I play vinyl because it sounds better, so much so that the designer of the best digital system I've heard once said to me 'Digital has such a long way to go...". The best LPs push similar dynamic range and nearly all LPs have greater bandwidth tha... 
Ringing new NOS tube, is it safe?
No- the circuit is fine. The tube is microphonic. It won't hurt anything, but generally microphonic tubes don't sound as good.If its still in warranty get it replaced immediately- most warranties are only 90 days. 
High value, high efficiency speakers for SET amps
A few comments.I also listen at lower than typical volumes. I frequently have to fight with salon proprietors to turn it down when I audition new equipment. In my case, those lower volumes represent realistic volumes. Bach cantatas are seldom perf... 
High value, high efficiency speakers for SET amps
So, Atmasphere,Then why don't we have manufacting that promotes high efficiency nominal 8 ohm or higher speakers. Seems like it makes amp manufacting funnel into a narrow "limiting" high power proposition that does Limit and force a specific choic... 
High value, high efficiency speakers for SET amps
The is no single type of amplifier that is the best for all genres of music, I don't care what amplifier it is, there's inevitable compromise somewhere. Charlesdad, while I appreciate many of your posts and your primary tenant (paraphrasing: 'get ... 
High value, high efficiency speakers for SET amps
Atmasphere,Rebbi's room is about 11x12, my office system, 14x16. Believe me, even true 92db, 8ohm, no problem. My 8 watt Coincident Dynamo is sublime with my 95db or 98db Lores depending on model. How loud do you listen? I generally like about 80d... 
RIP Kirk Bodinet SOTA
Sorry to hear this! 
High value, high efficiency speakers for SET amps
Generally with SETs if you really want to hear what the amp does (where the 'magic' is) its important that you don't push it past about 20-25% of full power.For this reason you usually need a really efficient speaker to show the amp off. In the ca...
