[quote user="oxric"] I just wished you would find it in you, out of fairness and common courtesy, to keep the thread within the boundaries within which it was raised, that is a technical discussion on the approach of Frank Shroder to the design o...

In general, DHT amps are lacking in power, dynamics and bandwidth. Would this be the result of poor implementation or rather a feature of such technology? If the latter is true, then it might on...

[quote user="manisandher"] My initial idea was to run just sensitive digital equipment and the preamp from the PP2000. But actually, there is no reason why I couldn't run everything (except the PC) from it. [/quote]
I went over the very same s...

Sorry, Anthony,
I do not follow what you are asking. What does it mean “panel meter on the DHT channel”?
My DHT channel has a plate current matter. I find it useful but not truly necessary.
My sited at 38mA for years and does not move. Hypothetica...

[quote user="Romy the Cat"]Again, it was very interesting, but… Let agree that methodologically you did not try Placette as it performance was masked out by you need to use your Neurochrome buffer to get gain. Your chain will sound as the worst eleme...

[quote user="guy sergeant"] I'm sure there are many bad implementations of the 845 and 211. Almost all of the commercially available ones are pretty mediocre. However I have heard good examples of both so I know it can be done. [/quote]
Actually I d...

[quote user="Romy the Cat"]The "Catch-22" with Melquiades is not the Melquiades price but the fact that I SPEND NO EFFORTS TO CONVINCE ANYBODY to build it...I made the Milq available and frankly speaking for myself, I feel more gratified that I revea...

Yesterday I got two emails asking me about Lamm ML3. I replied as I usually do, saying that I that I do not practice in satisfaction in audio-consumer curiosity. Still, it made me to think again about a hypothetic amp around GM-70.I am not a fa...

[quote user="cv"] I'm enjoying this account of Melquiades upbringing. I must ask though: how are you sure that what you are hearing isn't on the recording? Not that I don't believe you, I just wonder if the stuff has been there all along and undiscov...

Jessie, I have two comments/questions.
Are you sure that using the USB you do not use the sound card? I am a software guy not a hardware guy and with my limited understanding I presume that an application that reads a file must talk to so kind of dr...

Here's how I'd make a hard rear cover/rear chamber.I describe the process in detail, as it is a good investment of my time; I expect to have a similar condition and requirement for my own mid-bass horns (intended for use with AK-151s).This approach c...

Sine I read about the new Orion phonostage I was thinking about the whole story behind it. The whole Constellation Audio as the company that started 2-3 years back strike me as some kind of combined efforts of a group of dealer and distributors...

Well, I was thinking about that “Resonating Oops” for a while. I made quite a number of experiments. I some cases I was able to get interesting results but the “Resonating Oops” is very illusive. I do know that many readers of my site have wrong perc...

[quote user="rafaroxlm"]As you may know the 7788 is a high transconductance pentode which should in theory be able to give higher audio resolution than say 12AX7, 6072 tubes in tube mic pre designs. On search here the 7788 was mention...

[quote user="Romy the Cat"] The idea was very simple: to convert the C filter into RC filter, to employ the Silicon Carbide Schottky rectification diodes that showed themselves so nice in 6-ch Melquiades and to beef up the preamp with large bet...

Guys,
You really misunderstood this CD. This is just a compilation of GOOD MUSIC well performed and interpreted and it has nothing to do with audio. For instance now of my compilations CDs I ever played on my playback. Those CDs are good enough for ...

[quote user="Paul S"]I got new 6C33Cs for V2s from Lamm because no one else wants to match them, let alone match them for gain…[/quote]
There is no meaningful mutual conductance or bias matching for 6C33Cs (in context of ML2) besides gain matching, ...

I did not make my mind about it but I have some “concerns”. Using SS amps and hearing different SS amps I do not like their bass and the notion of a powerful enough DSET to be able to drive ULF in A1 was born. Sounds logical. However, recently I ...

It will be interesting to read how you will change your system, and I hope you will continue to include your "reasoning", as you have done to date, including "set-up music" that you use to establish the "stages of development" as you home in on t...

For sure an interesting devise, thank you Nick. I personally
do not like HD broadcasting. Some ideas that they have for FM is “interesting”
but in reality, it is hard to know what actuals sound is possible get from the
FM stages of this unit. I am...

I have lived with the Koetsu Onyx Platinum also and I agree. I did not really enjoy it very much in my system no matter what I did. However, honestly, when I first heard Koetsu many years ago (it was a Rosewood Pro IV), I was really drawn...

This is very interesting subject.
I expect that tghe new Midbass horns will have somewhere 108dB sensitively anechoicly. The driver is 99dB and the hyperbolic curve has much more EQ then Tractrix and that is more important the EQ that work mu...

A reader of my site sent me interesting information. It looks like Accuphase came up with a new model: T1100.

In this new model more functionality went to DSP, but the most important the ...

[quote user="Romy the Cat"] I do some very interesting experiments with Rohde & Schwarz tuner. Dima and I have discovered a way to use the Schwarz without the wide bandwidth amplifier, driving the Multiplex Decoder from the Schwarz’s preamps. Bas...

After exploring the options for Multiplexing decoding on digital domain I decided to downgrade this perspective for now. Here are some cone and prose of Digital Multiplexing as I can see them

First of all it was quite interesting and quite educational. Second of all it answers no questions but rather creates more questions. Here is what I try to compile some my observations and thoughts on the subject.
