I had today a long listening session. I listened a whole Mahler Second and I can tell you that I was the best upperbass I ever heard from a playback. I am not kidding. The upperbass literally despaired in the new room but what it is being called up...

I helped Romy shuffle around some hardware and connect some cables yesterday. That damned table weighs about 100.000 pounds. This was one of those once-in-a-lifetime opportunities to see live, in-person how Romy thinks about audio and incorporates th...

[quote user="drdna"]While I think a resonating speaker can add its own musicality to a reproduction, it is clearly adding harmonic distortion, etc. It may be pleasant, but you run the risk of needing differently tuned speakers for each type of ...

I keep thinking about my new idea of more than 2 channels
and room acoustic reinforcement but in natural and organic way, without using DSP.
I have invited my friend who did it from
last week to collaborate the idea and to bound some of my concep...

OK, this morning I tuned the playback and did some listing, trying to understand what was the problem. Sound was not just bad but it was very strange, it was almost as a mechanical replica of sound. I took my phase meter trying to set horns in ph...

Well, a few things that I need to note. If you or anybody else are trying to make an impression about own installation and use video then please make a relevant video. The video you made is irrelevant as it shows absolutely nothing. What is the purpo...

Thanks, JJ.
I do not necessary feel that it should be any difference between the early Hal-O production and the new version – they are essentially are the same products with different descriptions. For new dampers should be better only for lar...

A few days back I got a hold of an article in some kind of French publication and a site reader helped me to translate it. In the article Klaus and Reinhard reported that Arthur Benade’s helped them better understand the propagation of sound in h...

Another
very interesting idea proposed by a friend of mine with whom I just discussed the
notion. He asked if my find with center channel will work out then why wouldn’t
I use my Injection channels as a center channels, all that I need to do is to...

2011 will be a busy audio year for me. I will have a nice large space 28 feet x 20 feet x 11 feet which I am free to modify for audio. The walls are 150 years old irregular stone the floor is cement and the ceiling is composed of structural...

[quote user="Romy the Cat"]With the late success in my battle with electricity I was slowly reviewing some of my things. What I detected that in context of good electricity I can set up my Injection Channel much more aggressive, let seat 2-3dB more t...

[quote
user="anthony"]I guess I am lucky that the Bass Cannons can be run
off 9w from the DSET bottom channel and from memory I get about 115dB at 18Hz
once room reinforcement does its magic. One of the few benefits of a
small room. [/quote]

I did finish today the 2-driver extension for bass towers. I did not mount them to the default location – waiting for a “friend” to come to help me to do it. As I finish it will be exactly the same configuration that I had 7 years back in Boston.

The last night I “locked” Thomas to watch Masha and Bear in
my office and spent some time with playback trying to answers a few questions in
my head.
First, I needed to discover what was the source of the ridicules
double-sound that I exp...

Very nice, Keith, thanks. The most interesting would be to access the “Absolute Tone” capacity of the Gamma. Frankly I feel that with TADs it should not be very too advanced as they are at BMS/TOA domain, only with a little TAD syntactic twist. Even ...

[quote user="morricab"]…. putting the attenuator AFTER the gain stage has negative consequences for the sound….[/quote]
Well, yes and no. In the new 6 channels version of Super Milq I will be use 2 stepped attenuators: for Injection Channel and for ...

[quote user="Romy the Cat"]The subject of midbass nasal sound is very interesting. In addition to all OTHER aspects that might lead to midbass honk I would like to note that there is one that is in my view greatly overlooked – the precision of re...

user="anthony"]Hi Romy,
Further to my earlier message, I've measured the bias
voltages for the driver tubes in all Channels.
A -4.3V not adjustable
B -13.82V not adjustable
C -4.8V not adjustable
D -4.2V (ran out of potentiometer travel...

Part 2 – Description and explanation
Anyone who have ears and a rudimental mind to understand what ears register, and anyone among them who played with MF channels driven by SET, know that subject of SET loading is imperative.

Will I be listening to all my sources via the inverse RIAA?
Well, the question was sarcastic but it has some rational grains. If the signal passing via the 834PTF-Air does receive some positive attributes despite of the presumed nastiness of t...

Hi Romy,
I am planning my own DSET build. I have based my speakers on your Macondo and
am busy turning MDF horns in my spare time.
Once that is over I will move onto amplifiers. I plan to build a fullrange Melquiades for a
friend and the...

Gordon Rankin of Wavelength Audio did a series of one-stage DHTs with a step-up transformer input about ten years ago. I think they were called the Mercury series. By all accounts, they sounded good, but of course had limited gain, not much power and...

Romy,It is indeed an interesting subject; I am instinctively drawn to it due to the fact that the majority of orchestral instruments - the majority of my listening is orchestral/chamber/classical soloists - produce their own sound through the resonan...
