How I came to VMPS
« on: 12 Nov 2006, 09:25 am »
Warning: long, and possibly boring, article!


I live in the U.K. in a two bedroom flat (apartment). My musical tastes are mostly mellow, folk/soft rock (e.g. the Roches, Ian Matthews, Joni Mitchell) with occasional sorties into heavier rock (e.g. Barclay James Harvest, Free) and classical (e.g. string quartets, not full blown orchestral works).

My first real Hi-Fi purchase was in 1996: a Marantz CD63 KI Signature CD player, Audiolab 8000A integrated amp and B&W P4 speakers. This was set up in my living room but I knew nothing of proper speaker positioning, room interference and so on. I didn’t listen like an audiophile; I just listened!

In 2003 I decided that I wanted a better listening experience, and that this should come from headphones as I didn’t want to upset my neighbours (I’m a considerate fellow, as you can see!). So I bought a Headroom Blockhead headphone amp and balanced Sennheisser HD650 headphones. And a very nice sound I got. My ears were opened to the possibility that sound improvements were possible.

A visit to someone who had a dedicated listening room and was using a TEAC P/70 and D/70 CD transport and DAC plus Shunyata Hydra 8 power conditioning and cables got me well and truly hooked on getting a better sound. On trying these with my headphones I was particularly impressed with the quiet background (black, I believe is the term used). It is something I really noticed when going back to the Marantz instead of the TEACs (the Marantz being comparatively noisy). As I’d come into some money, I bought the TEACs, Hydra and cables.

It also occurred to me that perhaps I could use my second bedroom as a listening room. The size is a bit small, 13 feet x 8 feet x 8 feet, but I put all my gear in there to give it a go. By now I knew something of speaker positioning from internet sites, but even so I was struggling to get a decent sound. At first I tried the short wall and thirds rule, but eventually the best results were by using the long wall and a nearfield arrangement. I was pleased and thought I was getting a nice sound from my speakers.

Upgradeitis is a disease a bit like malaria: it comes and goes but once you have it it‘s there for life. This last year I have been afflicted by another bout and felt I needed to move my amp and speakers up a few sonic levels to do justice to the TEACs. I contacted my dealer, Angelsound Audio, and went round to listen in his house. I selected a couple of speakers and amps that seemed best for me and we went to my flat for more listening. My dealer was (diplomatically?) polite about the sound of my system (saying it was ’better than expected’!) but when we put his speakers and amps in the sound was dreadful! One of them was so bassy that it destroyed any musicality and the other pair seemed very over powering in the treble, even when turning the speakers to face away from the listener. Conclusion: the room needed some sort of correction in the form of base traps etc..

Room acoustics, another area to study if you are to get a good sound from your system. Some research on the internet and I ended up buying and installing some Auralex foam products. This made some difference, particulary to bass boom and a tighter sound.

Whilst on my internet travels I discovered digital equalizers; Tact, DEQX and the Behringer DEQ2496. The first two are high end equalizers, the Behringer more designed for live performance and mass production. It is also about fifteen times cheaper. I decided to buy a Behringer, learn about equalizers then perhaps move on to a Tact. The Behringer has been a revelation and is the single most important piece of kit I’ve bought. It takes some mastering but once achieved, a wonderful sound is possible. I cannot believe that its more expensive rivals can do much better.

Now I was getting somewhere. With the TEACs, Hydra, Audiolab and B&W speakers plus Behringer and room treatment I was getting a really enjoyable sound. I still wanted a better amp and speakers. My dealer had heard the VMPS RM30’s at a show and suggested these might suit me. More nifty finger work on my keyboard led me to the VMPS site and this one (the VMPS Audio Circle). I was impressed with the detailed notes on both sites, the reviews were good but how do I listen to them? I decided to take a big gamble, although I felt strangely confident. I would order a pair unheard. My dealer agreed and ordered a set for himself too! I also ordered a Son of Ampzilla amp as this too seemed an almost sure fire winner.

The Son of Ampzilla arrived first. My dealer came round with it and took the opportunity to hear some of his test CDs through my existing system. The improvements were good enough for him to immediately buy a Behringer! After he’d gone I installed the new amp; the proverbial veil or three were lifted off the sound. Brilliant!

And finally (finally???!) the RM30M’s arrived, my dealer bringing them round. There was no way I was going to let him set up my speakers. Anyway, he’s got his own to do!

Pulled them out of the boxes; no instructions so followed the set up advice on these pages. I removed a pea size piece of putty from each of the four passive radiators, then attached the base pieces and set them up in position. Had a good look and noticed a hairline scratch on one side; no other damage. (I probably shouldn’t have removed the putty, according to John Casler’s post of 5th August, but how was I to know? The L pads were set to 12.00 and 12.30 already and there were some instructions on the back of the speakers that mentioned this.

It took a while to get the right positions but eventually it seems that the best location is against the back wall (right up against the Auralex foam) as far apart as possible, 10" drivers pointing inwards, and toed in pointing to my ears. I also found they sounded better with the wave guides off. There was a hard edge to the sound, particularly noticeable on vocals, in the early days but as expected this disappeared after a few months so that now I have a really enjoyable sound.

It was, of course, a gamble to buy the RM30's and Son of Ampzilla without any listening tests, but then again, it wasn't! I've no regrets at all.

Hipper,

Not a boring article whatsoever.  In this hobby all of our system have evolved.  My first system when I was in graduate school was a simple three piece system:

1) NAD 304 integrated amp (at that time a Stereophile Class C component)
2) Sony CD player (don't remember the model number)
3) A pair of Cambride Soundworks Model Six Bookshelf speakers.

After graduate school I upgraded the system temporarily to a pair of Linn Index speakers with a pair of REL Strata III subs and upgraded the amp to a NAD C372.  That system lasted about 1 year until 1 of the subs died.  After that I started to explore the idea of getting a pair of tower speakers that would give solid bass and detailed midranges.  I remembered reading about VMPS during my childhood (Tower IIs, etc.) and was amazed to see that they were producing two ribbon speakers that were within my budget and that would fit in my living room: RM30M and the RM40.

After a couple of months of auditioning speakers (VMPS RM30M and RM/X at Obsession Audio ran by Scott Mayo and various other speakers such as B&W, Martin Logan, Gallo Acoustics) I decided to purchase a pair of RM40s with Auricaps in March 2006.  An excellent speaker with the most detailed midrange and treble that I have ever heard.  In September 2006 I sent Brian the drivers and crossovers for an upgrade to MLS maple cabinets.  At the sametime I had VMPS incorporate all other upgrades (except the PBS) into the rebuilt RM40s.  The new RM40s with Supermax OXO crossovers, SR71 treatment, TRT caps are absolutely amazing.  I recently upgraded my NAD C372 integrated amp (still using as the preamp) to a Bryston 4B SST and I could not be happier with the sound of the system.   This will be a system that I listen to for the next 20-30 years.  Someday I will probably get acoustic treatments and a DEQX2496, but those can wait awhile.

Best,

John

Great Post :thumb: An excellent story. Wish I could remember my whole story but my brain doesn't reach back that far :lol:

I'm very glad you did what you did. I also bought my first pair of VMPS speakers unheard back in 1996. My first thought was "what did I do" after listening to them, they sounded truly terrible.  Then with time and practice these speakers were amazing for the money spent easily outperforming my friends KEF 107/2s that cost three times as much. Even he had been very  surprised as he hadn't heard of VMPS. I only knew of them because of ads in the back of the now defunct Audio magazine.

I agree regarding the Behringer also. I'm not surprised your dealer bought one too. Once you learn how to use it properly the improvements for the money are substantial. It does such an excellent job that buying a Tact unit is far from a priority.

Hi Hipper,
I also owned Audiolab 8000A and was quite happy with it some 12 years ago or so. Actually it was among the best small integrated amps overall. However, a sound from Son of Ampzilla is huge improvement over it. Among others, I used 8000A with small Maggies and Spica TC60 (coincidentally, also assembled by VMPS at a time). Geniuses or not, some people certainly think alike.

I still look forward to my DEQ 2496. I hope to have it in a month or so.

As Warner said, while VMPS reveals it's high potential on a first listening, it takes some time to actually learn to extract their best.

If you need any help with the Behringer just ask.

Hi Hipper,

I also have an SOA and it is quite a good quality amplifier.  Over the past few years i have had a number of amplifiers in my system.  I did an extreme makeover of the ps audio hca - 2 which included many many modifications to the power supply i.e. nichicon gold caps, vcaps and blackgates in the signal path.  Audio consulting wire in the output stages and eichman pods as binding posts on the chassis.

I've also had the following amps in my system:

n.e.w. 20.1, n.e.w. dc66 ($3000us), aksa 100 nirvana plus and odyssey khartago.

The SOA is the best all round amplifier that i have  had in my system.  The hca - 2 does sound a little more transparent than my SOA but does not sound as musical in my opinion.

What preamp are you using?

Regards

Rod

Greetings Rod.

I don't have a pre amp as such. My TEAC D/70 DAC has a volume control and acts as a pre amp. The arrangement is:

  P/70 CD Transport - Behringer - D/70 DAC - Son of Ampzilla.

I also listen to vinyl occassionally, using a Thorens TD 280 Mk IV and Graham Slee Gram Amp 1 phono stage. The layout is then:

  Thorens - Gram Amp - Behringer (using its ADC) - D/70 DAC (which sounds better than the Begringer DAC I think) - Son of Ampzilla.

I don't use other sources like a tuner.

I've often wondered if introducing a pre amp would add anything but haven't done anything about it yet.
