Teddy Pardo Power Supplies

[Audiocom AV]

Audiocom are pleased to announce UK dealership for the Teddy Pardo power supplies for the Logitech Squeezebox Classic (SB3), Duet and Wadia 170 iTransport.

There is also a linear power supply planned for the soon to be released Squeezebox Touch.

The TeddySB3, TeddyDuet, etc, are designed around the new SuperTeddyReg and the incorporation of a very effective low-pass filter provides a theoretical ripple rejection of more than 120db over the entire audible spectrum and above 1MHz. Noise levels are extremely low, with approx. 57db noise between 1-20 KHz, that’s more than 1000 times quieter than the SB3 Switching Supply!

The power supplies come equipped with a high quality cable made of silver plated PTFE insulated wires. The cable capacitance is around 13pF/ft, and its resistance is also very low, around 10 milliohm/ft.

The Price for the TeddySB3, TeddyDuet & TeddyDock is £192.50 + VAT.

Details on the TeddyDock can be found here;

How much will the linear supply for the Touch be please Mark?

Hi Ali

Ok thanks.

Hi

Take a look at the noise measurements of the SMPS powering the SB3 against the TeddySB3;

The following graph shows the noise level measurements of the original wall wart power supply (red line), an alternative power supply based on a Liner Regulator (blue line), and the TeddySB3 power supply (black line). The brown line is a zero Volt reference which is actually the measurement equipment internal noise . AS can be seen the TeddySB3 power supply noise level is very close to the zero Volt reference.

I already use one of these supply's they are really good a very noticeable upgrade.

Hi Kirk

Did you buy the TeddySB3 before or after you had your SB3 modified by Boulder?

Cheers,

Hi Mark

I brought the Squeezebox already modified SH so never used it with an unmodified unit. Quite a noticeable difference compared to the stock power supply. I have also had the SB re-clocked, I am using a NOS DAC so no re-clocking and there are also no digital filters so it is quite sensitive to the incoming signal. Really quite impressed using it as a transport.

I have a touch ready TeddySB3PS and it definietly makes a noticeable step up with respect to the standard smps. This is in a Naim system. Much clearer.

Be interested in the same noise level survey taken on the spdif out of the SB with each supply. I suspect unless the internal switching regs are sorted in the SB the graphs will be very similar.

No problem with Teddy's supplies, just the way the info is provided.
