Thoughts on Cables

For awhile I’ve been using Van den Hul inter connects mainly D 300 Mk111s. It’s a good cable and the hybrid construction means that the RF “pollution” is very low. They give good detail and a neutral sound. I find they ae as good in my opinion as cables costing many times more. I like these cables or to be more accurate I don’t dislike them as I can’t hear them which is right for an inter connect right? Well, yes but.....

So why change anything? Well I suppose we are all experimenters in this field. Couple that, with the fact I got a chance to audition the Rothwell “The River” cables and it’s time to play about. When I opened the package I noticed how thin they were not what I was expecting as the considered wisdom is that thick cables are better, But is this true? Well with speaker cables, within reason, it probably is. After all, the higher current means you want as much cross section as possible and as bass travels through the cross section and HF goes along the surface, you want the right balance between number of strands and cross section. More of speaker cables later.

What are they all About?

The River inter connects are a high quality cable with silver plated copper conductors and PTFE insulation. For the technically minded Capacitance is 64pF per metre which is low. Rather than adopt the approach of using esoteric materials and unusual topology to combat RF interference Rothwell have gone for a thin diameter of (2.3mm) this coupled with the braided screen helps to reduce RF noise to a minimum, Construction quality is good with what are claimed to be . military spec materials. The Gold plated RCA connectors are quite springy and give excellent contact.

So how do they sound and should they sound at all?

This is the million dollar question as, they should make no difference at all and this part is totally subjective. Having now tried them on three sources, (Vinyl, CD and Tuner) and used them between Pre and Power amps what’s the verdict? Well you can’t hear them, they don’t have a sonic signature but, compared to the D-300 Mk111s to me there seems to be more extremes of frequency and a greater dynamic. This could well be as a result of the similar construction as I feel sure the quality of both cables is equally high. Certainly at only £55.00 per meter pair they sound “better” to my ears than a lot of super cables costing many times more. If these came in a flash box and cost £250.00 per .8 of a meter many would still think them good for the money. These are an unsung secret and well worth trying out. Certainly for me they have know become the reference against which others will be compared and the pair I have are now in permanent residence between the MC Transformer and the Art Audio VPS Pre-Amp.

Rothwell Moving Coil Transformer

My Koetsu Rosewood signature has arrived back and is now happily back on the Orbe. When I set it up I decided to try some new step up devices. I started, as recommended by Absolute Sounds, with plugging in direct to the phono input of my Art Audio VPS Pre-amp and increasing the gain by using the active setting. This was very good but for me no cigar. The Art phono input has always been good (their stand alone phono stages are legendary) and in the past I have used this with low output moving magnets such as the Grados with great results but, for me this did not match as well as I wanted. I knew what the Rosewood Sig was capable of and that is were I was headed. Next I tried a couple of Phono Stages including a Michell Iso a MF XLPS and a couple of others which were very good but, not quite right for me (though I almost fell for the Graham Slee).

I have to be honest always liked transformers for MCs Even though I used to design and make my own head amps in the early 80’s. I tried the Ortofon’s classic T-15s which are built into outsize screened phono plugs and might have settled for them except, I remembered I had I Rothwell MC Transformer in the drawer.

This is a well constructed unit in an extruded aluminium case with high quality gold plated RCA sockets and a nickel plated earth binding post on the rear. Internally two Mu metal screened transformer cans sit on a high quality circuit board. This screening should prevent stay magnetic and RF interference. The whole thing has great mechanical integrity which can only add to sound quality an prevent microphony. Gain is quoted at 24dB which should be adequate for any input. DC Impedance is I understand around 300 Ohms.

How does it sound?

I was sceptical as too how the Rothwell would perform as at under £300.00 it is £2000.00 cheaper than Kooetsu's own transformer in the UK. I plugged it in and dropped the stylus into the groove and instantly that lucidity I had been expecting was there in spades. Hugely detailed and dynamic with no sign of saturation. Paul Rogers voice on Bad Company's first album had a tangibility and Mick Ralphs's guitar seemed driving and rhythmic. The combination with the Rothwell seemed organic and right. On the Bach one knew the Violins were made of wood and not just cat gut. Jazz, Rock and Classical were all auditioned and combination with the Rothwell was not found wanting.

The only downside was a very slight bass lightness which I feel will be dealt with by impedance matching. when I have tried it out I will report further as, on trying the system with an Ortofon MC10 this lightness was not noted and the Rosewood Sig is more than a match for the old Ortofon in the Bass department.

Conclusion

A well made unit that performs well and sound very good indeed. If you have an amp or phono stage that works well on moving magnet try and audition this unit before spending any more. Highly recommended. For more info click here

Why Valves?

Have you ever wondered why valves are considered my many (including me) to be better for reproducing music and presenting it in a truly High End manner. The reasons are probably as numerous as the number of valve/tube amps on the market and I wouldn't pretend for a second that every valve amp is good (I have heard some pretty atrocious ones). Nor would I say that all solid state amps are bad (I have heard some pretty stunning ones in my time) but overall, a good Hot Bottle will, for me, beat a Silicon Sliver every time. Many have argued that it is the fact that valve distortion tends to be even ordered and therefore is in tune with the primary sound. Could be. Sounds pretty likely, in fact. However, when you look at the infinitessimally low distortion figures on many Solid State Amps today and in fact for many years, one would think that that would be pretty negligible. I do know, that to my ears, some of the hotter running transistor amps sound better than some of the cooler running ones, which may give us a clue in terms of switching distortion. Going back a good few years, when I worked for JVC as their resident Hi-Fi expert, I first heard (and had at home) their Super-A system. A pseudo class A system that raised and lowered bias voltage rather than switching it on and off. To my mind, this was then and if memory serves me right was one of the finest integrated Solid State Amps I have ever heard. Sugdens Class A efforts and Super Amps from the likes of Krell sound amazing. So why am I sitting here with just 7 watts a side of triode power driving my speakers? I think it is a combination of many things, including the large voltage envelope available to a well designed valve amp, allowing great scope for the cones to be moved accurately. The transformer matching, if the transformers are well designed, also means that the drive can be almost effortless, straining none of the components in the system. But I think that the most important thing is the sheer simplicity of valve amps, meaning that there is much less to get in the way of the music. Most of the extra circuitry on transistor amps, to my mind, is there simply to cope with the inherent defects of the devices and it is this very complexity which robs the reproduction of life. Now its fairly fashionable to like valve amps these days but I can honestly say that I was there a long time ago. Round about 1968/69, my father had the then state of the art Quad 33/303 System. I had a Garrard SP25 and a Teleton Amp, which I later traded for a Phillips with fairly decent Decca Deram cartridge in the
SP25's Arm. I remember taking a copy of Creedence Clearwater Revival's "Willy and the Poorboys" round to one of my brothers. He and his wife had a mono system which consisted of a fairly large Leak Sandwich speaker driven by the original Quad One and the associated mono preamp, whose number escapes me. This was driven by a Decca FFSS cartridge and arm on a Garrard 301. I was immediately struck with the lucid nature and detail in the midrange compared to what I had available at home, despite the fact that it was only mono, it still seemed to give a much fuller detailed sound and certainly was much less aggressive than the Teleton or Phillips amps that I had at the time and seemed to sparkle more than the 33/303 set up. Later, as I progressed along hte audio trail, I ended up with an Armstrong 621 Transistor Amp, which, to be honest, never quite "cut the mustard". My other brother had a Quad II/22 set up and when his wife expressed some concern that their new baby might touch the hot valves, I generously offered to swap my sleek 621 for their clunky dusty out of date valves - just in the interest of the baby, of course.... Shortly after this, I revalved these and remember cycling over to see the late Alex Shackman to listen to his KT77 conversions to these amps, which, fabulous though it was at driving the exceedingly efficient speakers of the day I eschewed in favour of the classic KT66s. Somewhat later, I built a system comprising the Quads driving open baffle 3 way satellite speakers and an 8 cubic foot sub base loaded in a manner that in these days would be described as Isobaric, using 2 Goodmans 12 inch base units. This was driven by a phase linear mono valve amp. The sound was exceptional and over 30 years later, a friend of mine who is a professional DJ, is still using it for his home system. The only other thing I can conclude, is that because the valve sound is easily re-established by revalving when the valves get run down, every 4 or 5 years, you effectively get a new amplifier for a very small cost.

What do I Listen to?

I got an e-mail recently asking me what I listen to? The obvious answer is music but seriously, what was being asked was what equipment do I use? Which is a valid question. On The main system, primary sources are a Michell Orbe SE/QC power supply with an SME Series IV normally this has a Koetsu Rosewood Signature mounted but, this went home to Japan for a factory rebuild. This sits on a Soundstage Developments isolation platter which, is something I developed for Loricraft / Garrard for use with their state of the art Garrard 501. Next is an Orrelle CD10T transport feeding a prototype DAC made some years ago by Tannoy but never put into production as far as I know. This is a Bitsteam device which to my mind still gives a smoother and more "vinyl-like" sound. However as I see all CD as a compromise and I like the sound of it it will stay for a while yet. Due to space considerations the tuner is a TEAC Reference 300 series with, of course, a quality roof aerial possibly the best small VHF/FM unit around with a neutral but full bodied sound unlike DAB which, frankly sucks.

These feed into an Art Audio VPS Valve Pre-Amp and then into a Art Audio Quintet MKII Power Amp which uses EL34 output valves in triode mode and is incredibly sweet while still being detailed and punchy. The turntable feeds into a Rothwell Moving Coil step up transformer which, is a sub-£300 gem (more of this later). Except for the tuner and turntable All components are fed mains via Black Rhodium mains cables these are fed in turn from a Monster Home Theatre PowerCenter™ HTS 1000 power conditioner. All interconnects are Van den Hul D - 300 III HYBRID except the pre to power amp which is Art Audio.

Output goes to a pair of Lockwood Academy studio monitors loaded with 12" Tannoy Monitor Gold Dual Concentrics circa 1969 topped with Tannoy ST200 super tweeters which are a fabulous combination. Also, on the maim system I have a pair of STAX SR-202 Electrostatic Headphones with the associated Energiser/amp

Cables are Pure Silver Sound Octet a cable from Arizona which is budget for pure silver and blow away some costing 10 times the price.

Placed in the A/V system rack for want of space are A Pioneer CT - 615 three head cassette deck and a 525a universal DVD spinner both these are patched into the Art Audio VPS and the DVD feeds the Sherwood Newcastle A/V receiver as well. This second system rack runs into an Epson projector, a Samsung flat screen TV and a Tannoy FX 5.1 speaker system with powered sub.
