TeddySB3 - PSU for Logitech SqueezeBox

More Views

Details

 The TeddySB3 power supply replaces the small wall-wart power supply that comes with the Logitech Squeezebox 3, and provides significant improvement in sound quality.

The design is based on the experience gained with the TeddyCap family of power supplies for Naim Audio equipment, and uses the same technology.

Sound

In general, you’ll experience more clarity, tighter bass, more detail, better dynamics, natural voices, better soundstage etc.

Performance

The small power supply which is provided with the SB3 is based on a technology called Switch Mode. Using this technology it is possible to create small, efficient, and low cost power supplies. Unfortunately due to their method of operation (high frequency capacitor charging), these power supplies are also very noisy, causing degradation in sound quality. As an alternative, several after market power supplies exist which are usually based on Linear Regulators. These regulators provides an improvement over the original power supply but as can be seen on the graph below are still limited in their performance.

The TeddySB3 power supply is based on a superior regulator called SuperTeddyReg and provides a significant improvement over linear regulators.

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.

Interconnects

The TeddySB3 power supply is 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.

Testimonials

"We had the Teddy Pardo PSU delivered a few days ago and it was promptly plugged in to a stock SB3. This is the most impressive linear PSU I have used so far for the SB3. A dramatic reduction in the noise floor, far better bass quality, improved openness and a notable reduction in hardness, edginess from the mid to high frequencies. All this without any loss of musicality, in fact the with the TeddySB3 there is a greater sense of musicality."


"Hello, PSU for SB3 arrived last week and I have to say I wasn't expecting a lot being that I already use an external Audio-GD DAC with the SB3, but I was wrong. The moment I put the PSU into action it was clear that this is not a small upgrade. The first thing I noticed was that the sound was clearer at low volumes as if it could go louder. But there's more better deeper bass, less sibliance and a wider soundstage. So this one stays and it makes me wonder if it's worth exchanging my flatcap 2x for one of your PSU's."


"The TeddySB3 finally arrived. The sound is much better than with the iomega zip power supply and a little device called a SBooster (some sort of filter made by someone here in Rotterdam put between the power supply and the Squeezebox) that I was using until now, which was much better than the stock power supply of the Squeezebox. The sound is much cleaner and detailed."


"On the Squeezebox forums, many users and devlopers claim that a replacement power supply unit will not make a difference to the SB3, there are contradictions to these views on forums such as Wigwam and Pink Fish.

When I initially bought my SB3 I was shocked at the small size and lack of weight the PSU had, and as a Radio Amateur I know how much interference a switch mode PSU can generate and cause interference in other electric equipment so I knew that just by replacing the PSU with a linear (transformer) PSU my mains electricity would at least be cleaner.

Whilst searching for a suitable replacement I came across the TeddySB3 listed on eBay, a little more searching brought back to the Pink Fish forums where I found another user had very good results. Undeterred by the fact the PSU cost more than the SB3 I placed my order. I actually had the TeddySB3 customised with a red LED to match the rest of my kit (NVA) and asked for an increase in amperage as I intended to purchase the Squeezebox Touch which has a higher power requirement. Teddy was very helpful with my order and from order to delivery took two weeks, bearing in mind that I placed the order just before Christmas and requested a custom build I think this was excellent service.

The TeddySB3 arrived quite late in the day and when removed was very cold, so left it for about two hours to get to room temperature. Plugged in, selected one of my favourite tracks....

Oh my god! the track that I knew so well had an immediate  level of silence, as if several layers of noise had been removed. A bit like cleaning the bugs of a car windscreen and suddenly every thing is so much clearer. Now I must confess that I do have a problem! I listen to clips of music, jumping tracks, swapping to the next album (I blame the SB3 and the remote control and my short attention span. However since getting the TeddySB3 I have not stopped a track... in its tracks and listening to the whole piece of music, something I have not done since my last turntable departed which was seven years ago.

After a few weeks of burn-in / warm-up and being left on continuously I switched back the the SB3 supplied PSU, what an awful mistake, bass was unclear, and everything else was just a mess. A matter of minutes before I switched back to the TeddySB3 - aah much better, no fantastic actually. A very happy customer and seriously considering an additional purchase for the Squeezebox in the bedroom."


My experiens with your super regulators.I  use a 5 volt for my squezzebox3, and a 12 volt for my nas server with very good results it is the best thing you can do for your equipment. My bass is very tight, and i have a very clean sound with lots of details, and now it plays the music so you can`t sit still with your feets.
