Steverino, don't forget that Romy's Placette line stage has VERY low output impedance. It might be able to handle even the shunt capacitance of 75 feet of cable with minimal HF losses. If the cable is 100 pF/foot then its reactive impedance is abou...

I have not seen it mentioned but I might of missed it. The PurePower absolutely demands shielded interconnects especially between preamp and amp in my experience. No matter how careful I route the cables, I was getting noise or buzzing from the speak...

It became customary that I make fan or blame in idiocy different industry reviewers, regrettably they give endless opportunely to do so by writing their incredibly stupid review. It also become customary that I follow what Lamm produces. I use to own...

The damn Milqs and everything else do a lot of hit and I have been running during the hot days a pair of small monitors with consumer-grade 100V A/B amplifier. The only requirement that I have that the 100V A/B is driver from my default preamp and I ...

Steradian,
I do not remember how much input impedance of my Placette is. I think I did ask to make it higher then 18K but I do not remember now, can measure if I were home…. In most of the cases the 18K is plenty but it very easily could be in...

This is what you need to know - these are the equations you need for a passive line level filter:http://www.t-linespeakers.org/tech/filters/passiveHLxo.htmlYou also need to obtain the input impedance of the power amps in order to calculate RC values....

I ripped my Cd player (to old to mention ) output stage and replaced it with SS J-fet phono preamp .I took RIaa components out .The dac puts out only 20mV so the MM stage with separate PSU and discrete J-fet regulators seems adequte for the job. Whol...

My system lives in a small room with poor acoustics. Fact of life until I get round to building the planned perfect music room which has been in design for 5 years and still is just a concept!Bass end is lumpy so I decided to try various solutions to...

[quote user="Romy the Cat"]So, what I am talking about is ability for an amp to have some kind of inner-algorithm that dynamically and actively “color” or better to say “dye” signals, still maintaining general color-neutral tendencies. Since I ...

Hi!English's not my mother language so I'd have advices to choose wich Melquiade could be the best for me...I read that there's a lot of different versions...and I wasn't able to email Romy because of the robot barrier.I've very good 95db Fullrange B...

Forgot to elaborate the Quad system.It is actually a tri-amp Quad system, below 100Hz is the Supravox 15in Field coil in open baffle, then it's a Stacked Quad ,and about 5Khz there were 5 RTR ESL cell. I did try the 6C33C amp in a single pair Quad by...

Just in time. After about 5 hrs of music on the preamp , I received today the 3 golden grid tube. Looking with a magnifying glass, I could not determined if it is gold wire. Anyway, I am burning the heater and will try out tomorrow. Here are some pic...

[quote user="jp"]In my experimentations, the da924 doesnt contribute much noise in my setup. Rather in my setup its the lavry ad122 thats the trouble maker. When all digital is turned off I have a very quiet background. Here are my observations...

Is there any abstract value to going for a preamp with a stronger output if you're using a passive xo at line level?I'd prefer to answer this question myself but i really don't have the budget to be swapping amps.How does a PLLXO interact with a non-...

Hi,
[quote user="dazzdax"]Hi Romy and other fellow audiophiles, what is your experience with passive transformer based preamps?[/quote]I have yet to find anything better. If using active try using a TVC as volume control, it takes the active preamp ...

I made the 543rd remodeling on the Opera room and move the video playback equipment to the new, I hope the last location. As I connected everything into PP2000 as it use to be (not PP2000+) but older not “Plus” version than I have some light MF buzzi...

It is even hard to critique because it is beyond of being ignorant of stupid. The John E. Johnson’s review of Lamm L2 preamp in the “Secrets of Home Theater and High Fidelity”. Below are the fragments of the John E. Johnson’s pearls… Each quoted stat...

[quote user="cb"] Also i stick a 30k resistor in R3 and the results are very good. [/quote]R3 is Milq’s loading resistor and it hardly to do anything with amp itself. Milq has own input loading is floating on the bias chains and it has a ...

Ever since the Melquiades schematic was published, I have been planning to build one, because the objectives and topology seem like they would work for my system. Unfortunately I am very much not a DIY person. Even though I have built my ...

I think I understant pretty well your descriptions and it's surprising the amp can overcome speakers flaws. Is this using the Lamm L2 or any other preamp, or just driving the Melquiades with the source directly? I wonder if that what you describe cou...

I wonder if you're doing your listening with the Bidat using its volume pot or you're using only vinyl with your phono correctors or maybe the ET-T-834 EAR using its volume pot. Maybe the Melquiades has its own attenuators. I'll be glad to know how y...

Thanks, Bill. The system you describe sounds like my brother''s old home theater surround sound, which did a nice job with 5.1 DVDs, for concerts, opera, and musical theater. I presently use only a turntable or CD/DAC source with my hi-fi, in stereo ...

Well, if you do not have anything user 35Hz and have low sensitivety then the passive might do. Still in future, when you feel comfortable with your passive unit you might for the sake of self-education try an following experiment: Guy Hummel use to ...

Hi Romy,I wish I had seen your post on Placette before buying mine. I didn't realize that there is no balance control on the unit. I know in theory this should not be a problem, but I miss this feature for several reasons. Can't hav...

Yes, my DSET is fundamentally the same as yours with 6 channels, three fullrange, 1627a for Channel C. The largest difference is probably that my DHT channel has its own B+.My preamp is quite different though, being a hybrid based on 10y. It has a ...

Paul, I do not think that “before or after RIAA losses” requirement has any merit as no matter what kind type RIAA filter is being used it always will lose around 20dB. I do not think also that there is a “safest path” or “reasonably affordable”....
