Dynavector XV-1s What is the REAL story?
So after careful set up ( Smartractor for alignment and microscope for VTA)  I have 50 hours on a new Dynavector XV1s. Using TW Acustic Raven and TW Acustic 10.5 arm. SUT is an Auditorium 23 T2, the correct SUT for this cartridge according to the... 
Microphonic from Vacuum Tubes?
I sometimes get a pop noise when a major appliance turns on….like the heat or air conditioner. I have 2 dedicated lines and it still happens sometimes.  
Upgrading power system
I have been closely watching Stromtank, off grid power supply. I believe you can find some reviews is Absolute Sound and Stereophile.    
Ultrasonic record cleaners
I bought the Humming guru ($400) direct from the South Korean company, for my Nephew. No scientific data, but it cleaned and dried pretty well. I would keep the VPI you have for dirty records, and run them through the Humming Guru after the VPI. ... 
Does Everyone Use 2 Phono Cables with SUT
Thank you all for the feedback and advice.    I learned an expensive lesson by using a regular interconnect with my SUT. I think @atmasphere is correct. “Brand” probably is not as important as the cables capacitance.    I’ll bet there are some ... 
Does Everyone Use 2 Phono Cables with SUT
Hi Jollytinker, You made my day. I’m glad this discussion was helpful. I find the Auditorium SUT’s to be stunning when used as intended. I’m still breaking in my 2 new phono cables and will report back shortly.      
Does Everyone Use 2 Phono Cables with SUT
As promised, I want to provide feedback after replacing the A23 “T1” SUT and  plugging in the Auditorium 23 “T2” step up transformer.   As a reminder my Miyajima Madake cartridge has an output of .23mV and an impedance of 16Ohms. It turns out t... 
Does Everyone Use 2 Phono Cables with SUT
Ok, now I’m really curious. I’m going to borrow my friends Auditorium 23 “T2” SUT. The T2 is made for cartridges  approx 6 Ohms and higher. By the way, I have the DIN phono cable AND the T1 SUT both grounded to the phono preamp. I will report m... 
Does Everyone Use 2 Phono Cables with SUT
I’m using an Auditorium 23 T-1 step up transformer. Sounds really good with the Madake and 2 phono cables. I am aware that the A23 “T-2” technically is for higher Ohm cartridges like the Madake.    I had been using a high-end “tinned copper” pho... 
Does Everyone Use 2 Phono Cables with SUT
Mulveling you are spot on. I was using a phono cable “to” the SUT and a “regular” interconnect from SUT to phono preamp. I have a Miyajima Madake cartridge (.23mV output) and the signal was literally getting lost.    I recently added 2 Audience F... 
Power cords or power conditioner
Hello Thyname, not shire if you have used tube traps. They have an absorption side and a reflective side. As you turn them, you get more of one or the other. For the ceiling and front soundstage, I use RPG skyline.      
Power cords or power conditioner
I would start with the room and speaker positioning then you can better determine the effects of various changes, like power cords and conditioners. By the way, I have a Torus AVR, replaced my Shunyata conditioner. Sounds great by letting the musi... 
Phono Preamplifier Redux .. Damn This is Getting Expensive
Spend some time researching the benefits of room treatments. I use ASC tube traps to control base and 1st reflections. Best investment I’ve made.  If I could do it all over again, I would have started with optimizing my room acoustics before buy... 
recommended speaker cables and interconnects
I have a tube system with high efficiency horn speakers. Mostly listen to vinyl. I read the Stereophile article that Art Dudley (RIP) wrote about Luna cables and decided to give them a try. Ended up with their Rogue turntable cable and interconnec... 
High Fidelity Cable replaces NPS 1260
Let us know your findings when compared to Total Contact. I plan to continue using Total Contact from my life time stash, but I may try this Q45-T on my nephews system.
