My experience with the First Watt F7
Hi @sns  and ​​​​@roxy54 , I have a similar experience to you with SS tube Push Pulls and SETs. SET sounds most natural, real, transparent and it also gives a good bass when it is well designed and used with height sensitivity speakers. Once I ... 
Solving the "complex music problem"?

Speaker cable recommendations
Duelund DCA16. I used it with my 300b SET and Altec 604e. I also have 20 years old Acrotec 1040 cable. I bought it bulk $100/1m. Acrotec sound a bit more refined but Duelund much more vivid, natural more musical.  
When were the best tube amps made?
Hi @atmasphere , Which modern 6SN7 are better than NOS? I currently use Ken-Rad VT-231 from the 1940s in the input stage of my integrated 300B SET. They are not the most expensive NOS but still to change the pair of these tubes is expensive for m... 
EMT 948 w/ 929 tonearm.
Hi @danmar123 , Don't worry. I had a similar issue. I had used this turntable without any troubles for 5 years. Then I moved to another home and setted-up EMT again. I started to recognize there is something wrong with tracking. At first I blame... 
EMT 948 w/ 929 tonearm.
From the user manual: Adjustment of Balance and Tracking Force ... This part is super important!!! I call it zero balance - "Set the tracking force adjustment level to "0". Lower the tone arm lift and turn the counterweight on the threaded tube... 
EMT 948 w/ 929 tonearm.
The issue is with the zero ballance when the VTF spring is set to zero. You need to set it correctly first and then set the correct VTF with the VTF spring.  
EMT 948 w/ 929 tonearm.
What kind of trouble? Even with 2.4g it should work good. Probably the zero balance is not set correctly.  
iFi iPower X - hifi bargain?
Does anyone compared iPower X vs Sbooster with Chord DACs? I tried MSRU LPS with 2qute. This combination sounded horrible.

Hi @danmar123 , Do you use EMT TSD15 cartridge? Here is high (VTA) adjustment gauge for  EMT 929 and TSD15. You can make such gauge on peace of cardboard yourself. The distance between armboard and bearing center is 35mm for EMT948.

I have EMT 948 with 929 tonearm. At first you need to check tonearm lift pad. It shouldn’t interfere to tonearm to go down and to the cartridge needle to reach record surface. The second is a dynamic VTF setup. You need remove antiskating and se... 
High powered single end 300b recommendations
I have Altec 604E speakers in a mid-sized room. The real sensitivity of these speakers is ~97db. I drive it with a 6 watt 300B DIY SET amplifier with EML mesh plate tubes. I did experiments with changing 300B B+ power capacity. I started with 100u...
