It is also possible that I'm reacting to a lack of true dedicated mid-bass. As previously mentioned, while the pair of 40Hz horns are under constructon, I co...

Recently, I have become aware of a strange phenomenon after lifting the tonearm at the end of the run-out groooves. The record surface noise keeps going when the stylus is no longer in contact with the record. I am using a Garrard 301 with SME 3...

N-Set,When I looked very briefly into the subject, as I was looking for some damping material to use in my tube preamp/phonostage, I contacted Gelmec who were very helpful and professional as a company. They will send you a small selection of sam...

So I ordered a Shallco switch from Nebraska:http://www.surplussales.com/Switches/SWRotaryAll-1.htmlAccording to some gurus at diyaudio.com endless Blowjob preamp thread,it seems to be the best human invetion after sliced bread.Let's see. If it's audi...

i checked out this product from your link(thanks).for digital inputs they show aes,spdif,toslink and bada,which i understand is for use with the rr hrx 24/176?.also there is no clear indication that the attenuation is achieved in the digital domain.t...

This is kind of strange but never played MiniMe loud. If I want the concert style play from audio I usually use Macondo. The MiniMe usually plays at the level of 60-80dB but today I have fun to listen something and I cranked it up. To my surprise Min...

[quote user="el`Ol"]BTW,the contemporary preamps are rather music servers with analog emergency operation.http://www.audionec.com/[/quote]Sure, to put HD, DAC and transport into preamp would make sense but I am afraid that contemporary music servers ...

It is not about a purpose or importance of a review. This guy set his review as some kind of topological exploration of LL1 operation. However, instead of it he copied the pages from Electronics for Beginners and said practically nothing that relates...

And email from a site’s visitor:….
“And for my full-range Melquiades, should I still try and build the original version or wait to see result of what you are working on now?”
This is a complicated question about 2-stage Melquiades vs. single-stage...

Romy,
Thanks for the advice.
Just to be clear here :
When you say
"Short the ML2’s inputs and the hiss should be gone"
I assume it is not a mistake, and that you mean short the unused input on each POWER AMP (as opposed to the PREAMP...

Macondo, because it is prodigiously time aligned has very nerow and well defined listening sweet spot. The only same identical listening spot I heard only from one another loud speaker, it was Wilson Alexandria which was very accurately time alig...

It might not be necessarily the new wire. With analog there are other billion reasons why it might not sound as it should. Still, I personally can’t stay listening “new” wire with MC cartridges. If you recently futzed with the arm wire then you...

It look like the project progress well. I have a little concern
about heat the will be building up in your PS enclosure. I do not know what
kind ventilation hole you have in there but be advised that it will be quite
hot. In worst case you mig...

Romy,do not spit in my eyes as I do have solid state PassLabs 350.5 but even with this 50W Class A amp (push pull) it is exactly the same problem if it is switched off completely even for a short while. I can take ~ 2 - 3 days to be back to norma...

[quote user="ghpicard"]Hi Romy, I wonder whether you could advance on the octal voltage regulator testing on the Milq, and what your conclusions were. As I have already seen Milq on your new home still with the 0A2s I can assume you weren't much sa...

Given that you are using a solid-state preamp with presumably lots of driving power, you might consider a 1:4 stepup and use of either an EML 20B tube or the AVVT AV8 tube. That might get you enough gain. I think Rankin used the 20B in his Mercury am...

Yes, I've been meaning to aquire such things for quite a while now.The biggest obstacle is that I think I need to format the drive and do a clean install of XP (or Vista).I did some audiophile trick with the system and since then XP doesn't acknowled...

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....

Brain, C’mon, I was kidding about the “Electron Intensification Interface”! There is nothing in this phonocorrector then a correct selection of tubes, thier proper (well almost proper) use and selection of the specific topological decisions that sold...

I wanted to compare a LP pressed at 33 1/3 and 45 RPM of the same music..To listen for any pinched effect or inner groove compression & distortion..Two identicle turntables and arms plus switching at phono preamp gave me the tool needed for this ...

Well, it looks like the new Berkeley's DAC moved from development and prototype into production. I most likely will have a change to trying in a couple weeks but I do not know at this point if I will do it. The final version of Berkeley's Alfa DAC ha...

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...

A few nights ago I slept in my listening room, on the floor and we were listening Bruckner 8… My floor in the listening room does not vibrate but as I lied on the floor (4” futon) I did pick up some bone vibration during the orchestra climaxes. I was...

Hi Domidaw, it looks like your amplifier is working pretty much correctly. The plate current in the output tube is a little below the recommended range (180 mA versus 200-280 mA in Romy's diagram) but too low is better than too high and you can adjus...
