A Discussion About What Level Of Analog To Stop At

So this is a bit of a friendly discussion, a sharing of information, and perhaps a bit of a what if thread.

As we acknowledge, the rooms our stereo’s reside in are a significant factor in how our audio systems sound. Now this discussion takes place mostly in the arena of speakers, and perhaps amplification for those speakers. I don’t believe I have read threads where it comes up in context to our source components. But I am wondering if it should?

In terms of myself, I only run one system unless you count my headphone rig. Truth is I rarely listen to that and I wonder if it is worth the money I spent there. But I am a consolidator and climber when it comes to audio gear. I also have an understanding with my patient spouse that I keep the audio gear in one room. I suspect if I tried taking over another room with audio gear, she would bury me in a shallow grave in the back yard.

So I have run of the living room within reason. Now this is the best room for audio in the house, but it is by no means perfect. it is 16’W by 20’ L with 8’ ceilings that are textured with acoustic popcorn. The flooring is short pile carpet with heavy pad. There is a dining room off the left wall, so only a half wall on that side. The right wall has a picture window in it. 6’L and 5’T. The back wall has french doors with glass panes. There is a little notch in the back left corner about 3’L by 1.5’D, its where they put a small bathroom on the other side of the wall. Equipment rack is on the side wall under the window. The speakers on the short wall on each side of a fireplace. Listen chair is 4 feet off the french doors.

Stereo consists of:

Martin Logan CLX ART speakers w dual Velodyne HGS12 subwoofers

Classe Omega monoblock amplifiers

Trinov Amethyst pre-amp (the DSP functions are a prime consideration in buying)

Cen Grand DSDac 1.0 Deluxe DAC

BPT 2.5 Signature power conditioner

Now all the analog gear is where it gets messy, and my consolidation thoughts are kicking in

Turntable #1 SOTA Cosmos Eclipse/SME V/Transfiguration Audio Porteus

Turntable #2 Scheu Analog Das Laufwerk No2 with Schroder CB-1L and Ortofon Verismo. Second arm Dynavector DV505 that gets used with an Ortofon MC2000/Ortofon MC3000 II/Kiseki Blackheart

Phono stages are a BMC MCCI Signature ULN, a standard BMC MCI Signature, and Esoteric E-03. Have an Ortofon T2000 SUT to use with the MC2000.


As a consolidator I sometimes wonder if all of this is necessary. The money is spent and this is kind of my audio kitty funds. I tend to keep those monies separate and often save and then sell pieces being upgraded to afford that next step. The reality is that often I cannot have to expensive pieces side by side and decide which I like the best. Since I also shop Audiogon and USAM for used gear it’s not possible to listen to candidates. As a consolidation I look at what is out there. For instance, when I tally things up I could possibly afford a Walker Proscenium that happens to be on Ebay at the moment. I would be down to one table, one phono stage, and two cartridges. One thing that stops me is that gold on the Walker is damned ugly, secondly, I am not sure I got room for the pump assembly. My system is a bit large for this room as it sits.

As I am writing I wonder if this room can really support a higher tier of analog gear than I got. I think some would argue that this room is limited in ways to compromise even what I have. The sound is very nice, better than I hear at many shows, and in other audiophiles’ homes I have gone to. We have a local audio group, and I haven’t heard anything I like better. In the past I have used the MC3000 II cartridge as a casual listening tool, but with the CEN GRAND DAC the sound is so nice I really don’t need to do that anymore. Still need the Dynavector arm though if I want to play the MC2000. Now all of these cartridges sound very very nice, and I could live with any of them. Truth is I like the Transfiguration the least. Or I think so till I spend about a weekend listening to it.

One thought is to choose one table and sell it all off and maximize that one. The other is to keep the Verismo and probably the Kiseki. Buy the very best table and arm I can with all the funds gathered once I sell all that stuff. The question I cannot answer for myself is ...is this worth it given what my room allows this system to do? I have a small amount of room treatment with wood diffusers, ART series acoustic panels, and the DSP function of the preamp. But I cannot turn this into a full-on treated room because of the basic limitations of it.

I have probably made posts in the past in other threads putting ideas like this forward. But I don’t know if I ever made a comprehensive post with all these thoughts. laid out. If you feel its repetitive, I do understand. However, if you have thoughts or ideas, I would surely be interested in reading them. Take the conversation wherever makes sense, as this is meant to be a wide-ranging discussion. Thanks for any of your contributions!



@mijostyn The Amethyst can do 48 dB per octave. I have to read the manual to find that menu. 

Interesting point about diaphragm excursion and unintended effects. Very reasonable points. 


Next weekend I will experiment with higher crossover points. I will look at 80 and 100 Hz. I can create curves for both and select between them. 



Excellent. Remember, any change you make will require taking new room control measurements. You will need to do this for both crossover points then you store both of them in presets.(I think?) This is a PITA but it is the nature of the beast and will take up the better part of a Saturday morning. 

 Once you have it set up. Turn up the volume and see how loud you can go before clipping. Check to see if you can hear voice coming through. You should notice a big improvement. The subwoofers should be located between the ESLs. If the subs are still obvious than the issue is with the subwoofers. Make sure all the subs extra functions are bypassed. If you can't bypass the low pass filter in the subs turn them all the way up. By 1990 or so I had become so frustrated with commercial subwoofers I started making them myself and I am on the 4th version. The problem is that is is extremely hard to keep subwoofer enclosures from becoming musical instruments. Turn the volume up with a bass heavy piece and put you hand on a subwoofer enclosure. It will be vibrating more or less at different locations. It will also be shaking a little in reaction to the speaker cones movement. With the ideal enclosure you should feel absolutely nothing, no shaking and no resonance. It turns out this is a very tall order. Mass alone will not stop it although it helps. Using opposing drivers to cancel forces helps a lot but is not enough. The enclosure has to be so stiff that any resonance is at a frequency way above the subs passband so the driver can not excite it. This is a lot tougher than you would suspect. Magico does it by using a heavily braced Aluminum enclosure. Not very elegant, but it works. 

I also forgot to mention that the Trinnov is trying to make the bass (350 Hz down) reasonably flat. Is is driving the MLs harder at frequencies where the level is not sufficient making the excursion problem much worse. It is also robbing you of power and head room. If you want a real head turner get a separate measurement system. It will display the frequency response of the system before correction. Your bass will be all over the place +- 5 dB or more!

I have a fairly elaborate system in one room. I can play vinyl, CD’s, Stream music and have Hi-Rez on a dedicated hard drive via a Bryston BDP3, Bryston DAC. Krell, Rel, Revel, CJ, Rega, Blue Heaven cabling throughout. Sounds great to me.

However, In my living room I have Amphion one speakers connected by Kimber 8tc cables to a Naim Unity Atom. That’s it.

I have lately found myself mostly relaxing in my living room and really enjoying the simple set up. I am reminded of that saying about the simple things in life.


OK, the question is why? Is the sound more to your liking or is the environment in the living room more to your liking, more comfortable. 

I spend most of my listening hours in the shop on a mid fi secondary system streaming from the main system over the local network. Sounds OK but not stellar.I spend more hours in the shop then my listening chair for obvious reasons.
