"D" amps, general discussion who's 1 and why?
Geph0007,I have a NAD 7020 I use as a spare in my systems when needed.Its a very gutsy little beast indeed, and it has served well in a reserve role when called on over the years, but the sound is quite rough around the edges compared to most newe... 
10 Levels of Turntable Mastery
Sounds reasonable. I'd say I'm about a 4 on this scale (minus my special abilities). Knowing me, that sounds about right.How about others? 
10 Levels of Turntable Mastery
I have telekinetic powers and can make my table spin at a constant speed better than the best DD turntables, although sometimes I get distracted and all hell breaks lose! 
How to reproduce sound of piano
"Krell does a good job on piano"I've heard the $2500 Krell integrated do a very respectable job on piano music with Martin Logans. 
Subsonic Rumble Solutions
Eldartford,I've seen the Ohm sub bass activator device. It is a rectangular circuit board just a few inches in dimension that connects between crossover and woofer internally as I recall. I ordered a pair and installed them into my Ohm L's as an u... 
How to reproduce sound of piano
"Grados GS-1000 headphones actually does very good job with piano (much better than speakers)"Doesn't surprise me.On the scale at which they must operate to produce realistic SPLs to the ear, the wide range drivers in headphones are physically muc... 
How to reproduce sound of piano
Off the cuff, I'd love to hear a properly functioning pair of full range Ohm Fs sourced from a very good Class D amp like say a Rowland set up properly in a moderately large room with any quality digital or phono front end for a shot at doing pian... 
What cartridges under $800 outperform DL-103R?
To better a 103R in that price range, I'd be curious regarding the enhancements Soundsmith or others provide for the 103R itself. 
Ohm Walsh Micro Talls: who's actually heard 'em?
"quick impressions reveal that the tonal balance of the speaker shifts noticeably with my Prima Lunas "That is what I would expect with most tube amps given the variable impedance of the Ohms at various frequencies as I understand it.The CLass D B... 
Subsonic Rumble Solutions
FWIW, some speaker manufacturers build subsonic filters into their speaks as a way of tightening up the low end by filtering out low end frequencies that the speaks are not designed to reproduce accurately. That is another possible reason why some... 
Ohm Walsh Micro Talls: who's actually heard 'em?
Marty,Interesting results with the tubes and Class D. I'd be willing to bet break in is a factor still at this point.Imaging and dynamics improved significantly in my system with intro of the Audio Research sp16 tube pre, so I suspect some of what... 
2-way speaker with best bass

2-way speaker with best bass
Ohm Walsh speakers are a very unique design for getting the most out of 2 way.The wide range Walsh driver fires downward and the sound is emitted from the rear of the driver 360 degrees. There is a large surface area available with this configurat... 
Ohm Walsh Micro Talls: who's actually heard 'em?
Marty,Which Bel Canto specifically? Is it a Class D? Does it double or near double power into 4 ohm?Also it appears you've had the 100s for about a month. Very possibly they are not fully broken in yet? Dynamics on my Ohm 5's improved dramatically... 
Reason for buying old/classic turntables
"my opinion is that belts have compromises, direct drive, properly exectuted, does not have compromises"Ok, but what facts is your opinion based on?The drive turns the table at a constant speed. Other than this, what else does it do to make the so...
