Tonearm Alignment Conundrum
@lewm Good point! It is solidly in there. I will try other headshells with this arm.

Arthur Salvatore's website, High End Audio, has an extensive list of LPs, all graded for sound. He listens almost exclusively to classical (he claims that there aren't any good sounding rock LPs). His websire is enormous. Most of it is his impres... 
What Power Amplifier Should I Buy?
After all this discussion of power, I bought a Bryston BP-17 cubed preamp. I'll get it next week. This discussion has convinced me that I have enough power from my power amp. So I decided to see if the much newer BP-17-3 can outperform the aged Le... 
What Power Amplifier Should I Buy?
@jaytor Yeah, I have always had concerns about the EQ. But some form of EQ is needed to help tame some of the FR variations from the room. I have traps which are very effective. I don't need more, except for the floor to ceiling mode. But the "ru... 
What Power Amplifier Should I Buy?
@scm I deliberately crossover at 100-120Hz because of a nasty room resonance at 40Hz. This creates a big dip at 80Hz that can't be EQed away very effectively. This dip is very strong with the f208 speakers. It is much smaller with the sub. I've pl...

@jimmy2615   @perazzi28  I've talked to Bryston about bi-amping. They recomment against doing it because the speakers drop below 4 ohms at the xover to the highs (2.2 KHz), although they hedged saying I moght be OK because there's not much power/...

@soix Hi, I can understand your frustration. Please tell me how I can clarify. I would like to keep seeing your inputs to my questions, even if it is not complementary. I value what you have to say. I cannot explain why this XP-12 was a failure ...

@jbuhl Hi, see my system pics. Room dims are there.  
What Power Amplifier Should I Buy?
Wow! So many great ideas. I appreciate how these posts have recommended changes to other components, so much so that I thought I would discuss my system in a bit more detail. The Paragon System E is used as a Phono pre only. It creates a beautif...

@ditusa Thanks for showing me an alternate path. Could you explain how a second sub improves the imaging and sound stage? Perhaps I used the wrong word. By "oomph" I meant more power for transients. I wasn't indicating that I needed more bass. I ...

Pass Labs found a gain module that was out of spec. The preamp was manufactured in 2019. Passed replacd the module with the current production module and tested. My XP-12 is now in spec. I've not set it up in my system yet. Pass was very respons...

@jji666 I've measured signal levels throughout my system with an AC voltmeter, osclloscope and RTA. The measured input and output voltages are well within normal range for each component. I hope that Pass has an answer.

I've taken the xp-12 into the Pass factory. Kent gave me a quick tour of the production area. I explained my observations and measurements to the tech who will be testing the xp-12. They've had it for about a week. I do hope they have found somet...

@asctim  No. Distortion is audible and clearly present on REW data also.

@audphile1 You have a great suggestion. Please check my analysis below: Shelter 901 output is 0.5mV at 0 dB. Zphono gain is 60 dB (1000x). So the input to the xp-12 is 0.5V at 0dB. This is right in the sweet spot for input. 20dB more might cause...
