Balanced Pre for Bi Amping Recommendations Please
Used, the Sonic Frontiers are balanced and SFL2's have dual outputs in XLR. I think the Line2 and Line3 do too. Factor in replacing tubes with NOS.One of the most versatile preamps is the PS Audio PCA2, which goes for around $700 on the 'gon listi... 
Pre-Amp For Plinius Power Amp
The Plinius has normal input impedance and fairly high sensitivity so it can be matched with everything from tubes, SS or passive. Maybe, use no preamp at all if you are just using CDP and find one with variable output. There are very few amps tha... 
Up-scaling DVD player that responds to mods
Philips 763SA SACD/CD/DVD. If you can deal with surface mount, upgrade the output analog opamps, bypass the caps and I'm told it competes with 5K CDP's. If you have passive preamp, imagine a 2 ohm output impedance with Borbely VFET buffers and scr... 
Can I use ECC88 for my Sonic Frontiers Line 2?
Recommended by Parts Connexion and have tried that myself with all 8. Much better highs and imaging. 
Removed sofa, thought I needed more bass trapping
This is a tough question. Obviously a big foam couch is going to absorb mid to high frequency and will affect a room. Usually, the rear wall and corners is the right place for bass traps.My research on bass traps is the only effective way to make ... 
Any Opinios on Genesis II.5
I've got the lower 350's and they are on an entirely different level from anything I've heard before with the possible exception of Wisdoms set up properly. The bigger Maggies come close but not nearly the range. Quite simply, they're the closest ... 
Can a simple DIY volume knob replace a pre-amp?
There are 3 basic analog volume controls. Potentiometers are the least expensive but capacitance and inductance can affect the sound. There are some well regarded brands such as Alps. Attenuators use individual resistors and can be anything from s... 
Problem with AC and how to solve it
The mechanical noise of a transformer may not affect the electrical at all unless it is the noise is caused by severe overloading In that case, current can vary. Roughly 50% of transformers hum naturally or because of the poor quality of electrici... 
Isolation Transformer
Acme, GE, Square-D. Shielded is recommended but not essential. If it's going to be in living space, go for Q rated for no hum. For a few more bucks, consider providing balanced power but derate the output by half. Equitech's site has some useful i...

Problem with AC and how to solve it
BigTee had one of the best responses I've read on the site. I remember a halogen standing lamp that had me convinced it was a ground loop and a single misplaced power cord too close to an interconnect.Consider getting an electrician to test your h... 
Power matching while bi-amping
My old attenuator is available along with solid RCA Y-connectors. All it would require an extra pair of ICs. It is a stereo attenuator ranging from 1k to 4k and has additional 3-way switch that adds another 3k, 6k or nada. All in a cheesy, small D... 
Review: Aragon 8008 BB Amplifier
And here I was expecting you to compare it against much more expensive amps.Welcome to the club. The Aragon has always been a great value. Although the BPT products are very good, you might want to reconsider a toroidal isolation transformer. You ... 
Power matching while bi-amping
With an RCA adaptor, you can use a resistor on the positive side. I would recommend using an attenuator with 23 resistors for each channel up to 5K because gain might not be equivalent for all volume levels or between CD's. Pots didn't work well f... 
Passive biamplification questions
You didn't say if you were using identical amps.Using identical amps vertically will not increase perceivable power much since most of the the power is used by the woofers. However, the drivers can interact with the amp and with each other. Biampi...
