What Power Amplifier Should I Buy?
@lynn_olson  I agree that another sub would help. I'm confused by your statement about power requirements. Did you mean to say that any amp over 100 W will push the drivers into compression (does this mean non-linear?).  Therefore any amp over 1...

@erik_squires  Moving the EQ to the sub path is a good idea. I do however, make adjustments to frequencies higher than the 120 Hz I now use as XO. What kind of measurements are you referring to?  
What Power Amplifier Should I Buy?
@kennyc  Just looked at Bryston's published spec. It is rated at 180 W into 4 ohms. So it is rated at 4 ohms. However, I was cautioned that if the impedance was below 4 ohms for a large part of the spectrum, especially in the midrange, there coul...

@kennyc  Thanks for reminding me about this. I've seen the impedance plot on ASR. There is a dip to 3.7 ohms at about 100 Hz and 3 KHz. I also measured the voltage into the speakers while I had the SPL at the listening position using pink noise....

I'm not sure if anyone is still paying attention, but... My time with the BP-17 has come to an end. I could not get rid of the sibilance that drives me crazy. The ergonomics are OK, but nothing like the Levinson 38s. I've listed it, but not on Au... 
Bryston BP-17 cubed or Benchmrk LA4 Preamp
After all this preamp testing, my pocketbook is a bit lighter but I have  learned a lot. The smoothest, sweetest, most pleasing sound is from a 1980 vintage Paragon System E tube preamp that I bought years ago new. I recently rebuilt the external... 
Bryston BP-17 cubed or Benchmrk LA4 Preamp
Well, here's an update on my exceedingly frustrating search for a new preamp. I've listened all month to the used Bryston BDP-17 cubed I bought a month ago, It took a while, but I've concluded that it too produces a sibilance that I just can't st... 
Bryston BP-17 cubed or Benchmrk LA4 Preamp
@jc4659  This is a very long overdue update. I bought a Bryston BP-17 cubed last week. I'm head over heels pleased. What happened to the used Pass XP-12? Right our of the box, t heard a lot of sibilance and other high frequency screeching. I sen... 
Tonearm Alignment Conundrum
@lewm I popped a few headshells into the arm today. Since I wasn't looking for an alignment, I put a level on top of the HS with the arm on its rest, locked in. I was looking for differences. All five of the headshells I measured have shown the s... 
Tonearm Alignment Conundrum
@stereo5 The overhang has nothing to do with my current problem. Judging from the number of posts, you are probably very knowledgeable on the care, optimization use of audio equipment. Therefore, you will understand that there are three alignment... 
Tonearm Alignment Conundrum
@lewm Good point! It is solidly in there. I will try other headshells with this arm.  
Truly Stunning Vinyl Album
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...
