What Power Amplifier Should I Buy?
@lynn_olson  I've dragged my Levinson no 27 Power Amp out of storage. It is now 30+ years old. I have had it for 20 years. A few months ago, I replaced all the big power supply caps (8 of 'em) with brand new ones and thoroughly cleaned it up. I b...

@lynn_olson  I forget if I had posted previously that I am running a single 15" HSU sub right now, 800W plate amp. I xover at 120 Hz using a K231 from Sublime Acoustic. The two channels are combined in the sub.That value is higher than most recom...

@lynn_olson  I will probably buy the Buckeye Hypex NC502MP 2-Channel amp. Spec is 500W in to 4 ohms at 1% THD. I'm not happy with that way of specifying, but the power should be far more than the Bryston and should allow me to discover what more ...

@lynn_olson  @atmasphere  I've enjoyed this discussion. I have built my own full range speakers in the past. I understand how difficult a task it is. I can get one of the Hypex modules and check it out. Past that I really can't afford even one...

@lynn_olson  Thanks for the recommendation. Gee, those are some expensive speakers. My budget is $5K. I need to stay near that price. What is your opinion of the Revel f208 speakers? I bought them mostly because I liked the small bookshelf spea...

@lynn_olson  @atmasphere  My thanks to both of you. I agree with all that was said. I agree my speakers are mostly 4 ohms. My previous measurement indicated that even for the 4 ohm load, the voltage I measured at the speaker input terminals (pin...

@erik_squires  Thanks for the suggestions. I use REW to characterize and help me improve my sound system. I have extensive traps from a company called "Real Traps". I know where the resonances are. I understand that dips in FR are hard to compen...

@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...
