Back to the resistor bake-off - written by jaudioresearch

Before I started my tests, I did put around 2 days of music through each resistor to give it some burn-in time as some manufacturers do recommend. Two days, in fact, is not much, as some people claim, that let's say Path Audio resistors take...

In this blog we see one of our Glasshouse passive pre-amplifiers being combined with a 48 step 10K Khozmo Stereo Series Stepped Attenuator. 

 

In the words of I.L:

The Capacitor Bake-Off - jaudioresearch

 

Back to the Capacitor Bake-off - Written by jaudioresearch

 

I have built 3 exactly the same DAC boards, except 3 different types of electrolytic capacitors placed after the voltage regulator, forming CRC filter just before DAC/receiver chip. I need to say that I don't always like using the same type of caps in DAC...

The Bristol hi-Fi Show 2020

The Bristol Show is probably the largest of its kind in the UK. Located at the Marriot City Centre Hotel occupying 7 floors. Celebrating its 33rd year. Mark and I drove down on Friday to see what goodies were on offer.

After an easy 2hrs 30mins drive we parked up at the Caboot Circus Car Park as we would normally. The car park is just over the road from the Marriot and close to Wogan...

Warsaw Audio Video Show 2019

 

Here we are again... Last year we were so impressed with the Warsaw Audio Video Show in Poland we decided to return for the Weekend of 8th - 10th November 2019. What is now referred to as the 2nd biggest Hi-Fi Show in Europe is located in 3 venues. The PGE Nardowy Stadium occupied 2 floors of the Eastside and one floor on the West. One more than last year so the show is definitely...

 

When asked by a customer about the sound difference between the Psvane 300B Western Electric Replicas and the new Psvane ACME valves I had to decline to comment as I hadn't had the chance to listen to the new ACME yet. As Mr B is such a valued customer I offered to lend him a pair of each so he could make up his own mind, as long as he could report back his findings. He gladly agreed...

 

 

When we opened the doors of Hi-Fi Collective Ltd (HFC) over 16 years ago, our original intention was to design and sell valve and speaker kits. However, we quickly came to realise that there was a shortfall of component retailers so we focused on that aspect of the business. However, this didn't stop us from finishing our Glasshouse 300B single-ended kit as initially planned...

The 2019 Audio Show, Woodland Grange, Leamington Spa Show Report

Woodland Grange is one of those locations that’s equally convenient for everyone and great when you get there. Rather than being South-East orientated its accessible from London, Reading, Birmingham and further North/West. I bumped into visitors who wouldn’t normally be able to make it to a London or Windsor/Ascot Shows but were enjoying the Audio Show at Woodland...

Bottlehead Crack Headphone Amp - Build and Modification

This blog post was sent in by a loyal customer, R.T. reviewing the Bottlehead Crack Headphone Amplifier kit and detailing some of his very own tweaks. In outline, US-based Bottlehead has been creating valve kits for some time and have a good following. This kit is their all new output transformerless valve headphone amplifier featuring the double triode 6080 valve. This kit suits high...

Kaisei First Impressions

This weeks blog comes from F.C. in regards to some recently purchased capacitors:

 

"I received today, among other parts, three Kaisei 4700uF/25v. Two for one of my gainclones and one for an old dac psu, feeded by batteries. 

 
I must report that I am very happy with the sound.
I allways used Silmic or Mundorf, where caps have an important influence...
