Cleaning records.

I have tried cleaning records in various ways over the years.

From tap water and washing-up liquid which can leave a calcium residue to wood glue which  can get stuck in the grooves where spread too thinly.

I recently tried Covid hand sanitiser rubbed gently into grooves with my finger tips and used warm water to rinse it off. This works very well and leaves no calcium deposits. By using finger tips one can feel how much attention each record needs before it becomes clean.

Funk Firm Houdini Mini Review – Nov. 2020

The Funk Firm Houdini has added focus, lowered distortion, improved dynamics slightly but, most importantly, the music now floats out of the speakers in a way digital never really manages. This is in quite a high-end front end. Without exaggerating, I would compare the effects to a successful £2000 upgrade or 25% improvement in my set-up and I have had over 40 years of experience in getting the best out of systems. What is particularly interesting about Houdini is that I can’t think of an upgrade in any part of the Hi-Fi chain where quite that same improvement in space and perspective within the soundstage is achieved. The music sounds closer to the real event rather than just different.

Now stocking Houdini as I have been so impressed!

Damage to New Records

Record sleeves even with specialist pressings are often made of cardboard and put fine scuffs on the records every time they are removed. This can cause surface noise. E.g. Aldous Harding – ‘Party’ my most recent buy. I have had to buy plastic-lined paper inner sleeves which work well but the original cardboard one doesn’t fit alongside them.

 

Turntable DC power supply

Minimalist turntable DC power supply with adjustable speed control.

Can run on battery.

Built on maple and ebony block with Black Gate capacitors and 2W Audionote tantalum resistors.

Wired with flat silver in cotton sleeving.

Excellent sound quality!

4 ohm speakers and effect on power delivery.

I often get asked about this and some speaker manufacturers like to avoid stating average impedance when they quote speaker sensitivity…

In 2002, Paul Messenger described beautifully the paradox of 4 Ohm speakers.

‘Over the years, speaker makers have tended to evolve their designs to suit the typical transistor amplifier which is essentially a voltage source with a low source impedance.

Halve the speaker’s impedance from 8 to 4 Ohms and the speaker draws twice the current and power from the amplifier. This extra power gives an increase in apparent (though mythical) sensitivity. Once one manufacturer adopts the strategy, others feel obliged to follow.’

A 4 ohm speaker actually draws 2W when provided the voltage required to provide 1W into an 8 ohm speaker so a 93db 4 ohm speaker is no easier to drive than a 90db 8 ohm one!

Gold Note CD-7 with top of the range Favard upgrades – £1200

The compact CD-7 was always very musical.

This is a custom-built one-off Gold Note supplied to me with upgrades from the top of the range Favard including its Burr Brown PCM 1792A DAC, components of its power supply including the power regulator and OP as well as the Clock.

The idea being to have a really compact CD player of superior quality.

DIMENSIONS: Width 200mm  x Height 80mm  x Depth 260mm

Superb and at my cost price.

Currently has Electro Harmonix 300B Golds.

‘SME’ RCA plugs.

Many years ago I used to curse the overly complex 4-5 piece RCA plugs which were often referred to as ‘SME’ plugs.

I don’t know if SME made them but they were dreadful.

Often attached to arm leads the wires would shear, come loose and cause all sorts of intermittent problems.

The screen wires were trapped by a threaded portion which would soon enough break off the filaments or develop a loose connection.

To my surprise, some Chord cables use a similar design of RCA plug with a plastic outer casing.

My Chord iChord lead has been very unreliable with the centre pins sometimes sticking in the socket and the plastic body sliding off the plug (hence the ugly glue fix) and the same issues with the screen- pinching piece needing tightening and the screen coming detached.

Now, the last straw, the earth has sheared causing a rare drive-unit to be blown…

 

Peerless 100-20 co-ax drivers – offers

Rare 9 inch drivers with tweeter on frame in front of bass-driver dust cap.

Alnico magnets.

Not the first time I find a good co-axial driver outperforms a good full ranger. E.g. Visaton B200, Fostex etc.

Peerless did not bother replying regarding driver parameters but sensitivity seems very high – about 95db.

Original Jensen caps (which measure fine) supplied but have replaced them just in case. – see image.

Audioflair

There has been some confusion about our status. We never traded as Audioflair Ltd. We applied to be a Ltd Co to protect the Audioflair name but it remained dormant until it was voluntarily dissolved by us in 2016.  I have always been a sole trader and still am.

Croft amplifier logos and badges £1-£4 each

Selection from old ranges.
E.g. You could change Absolut, Charisma, Epoch Elite, Vitale knob surround label to gold, silver or purple for a new look. I also have a 2 hole stereo pot version of the label available.
I have a few logo lenses too.
Or just replace your missing labels.
