Help - Need Preamp under 5K for Class D amps
You might add these to the audition list.TRL Dude $3500First Sound Presence Deluxe MKII $2400-4800Cable Co,has a pre coming out,it was in their last "update" e-mail.They have the linestage and were waiting on the phono-worth a call. 
classe power amp or pass labs x250, x350??
I would vote for the Pass amp.I like the "sound" better and it should mate well with the B&W N series. 
What is your favorite type of tweeter?
It depends on what you are trying to build.Especially the bandwidth of the midrange driver.Do you design similarly to the Scaena,with minimal crossovers or use steep filters and phase compensation.Many variables. My first thought would be the midr... 
Need Rec on $3k or under Preamp
First Sound Presence Deluxe.Easy tube rolling-one per channel. 
for multiple driver arrays, how to calc capacitanc
I believe that you want to square the number of drivers to keep the impedance at 6 ohms.The cap would be the same for 1,as 4,9,16.This would allow for a single cap,prior to the series-parallel arrangement. 
Old Classe pre-amps vs. new?
You are compaing the old/Dave Reich to the non-DR designed units.I prefer the older units.Maybe slightly darker,but have a little more magic in the mids.My vote goes to the DR-5/6. 
Hi/low sensitivity and ground toggle switches???
The hi/lo might be phono gain.The ground toggle is to eliminate ground-loops. 
What is your favorite type of tweeter?
Gallo CDT,Fountec,Accuton. 
Cable question
If you don't like the "active bias",why don't you try a model w/o the biasing-same line of products. 
amp and preamp... i'm getting close
Get an integrated unit (amp/pre) and invest the left-over in a phono stage.Reduces the necessity of another IC between the amplification.Just my 2 cents. 
need help selecting Oppo
Oppo website-hit the compare button and you should find your answer. 
Using platforms / shelves under floorstanders?
Have had good success with a platform placed under my speakers.The material used to couple this platform to the floor will change the perceived sound.The best option IMS was the triple-point. 
S/PDIF sounds more analog than AES/EBU
While making a comparison,it is easy to toggle between two cables to make a decision.But, if both cables are in the system,they will affect one another-as they both will present a load to the transport and/or dac. Indepently evaluate each cable,on... 
S/PDIF sounds more analog than AES/EBU
You should audition each cable separately.If both are connected and you are flipping a switch,then one is contributing to the other-both are "in the circuit". 
Sanders sound or parasound for big ESL's
Yes,the 300s can be mono'd.I had Roger convert two stereo units-definitely no clipping there.
