I did a frequency response test (using miniDSP EARS & REW) on my SMSL SU-8 v2 DAC and found that the phase performance is strange. I used 2 headphones: Sennheiser HD650 & Hifiman HE-4XX, both single-ended. I also compared the SU8 to 2 other DACs: Grace SDACB & XiangSheng DA-05B. All DACs were...

I received the HF2 a couple days ago and have been enjoying them. In the meantime, the GS1K has been hanging on its stand, naked and forlorn. The huge foam bowls have been deteriorating to the point where listening means ending up with a black ring around my ears. So the bowls came off. I...

I guess I'll be the one to start this thread on the SPL Phonitor model 2730. (Including Auditor model 2910.) From discussions on this amp, I think quite a few of us own or are planning to own it. Please share your serial number, your setup, what you're learning about it, questions & answers, and...

Hi. I just purchased a used HRD Portable Amp (sans DAC). The handwriting on the label, on the bottom, isn't completely legible. I think it says "2/1/07" and "211206." It came with a brick PS (model APS48-ER-125) that connects via a 5-pin DIN on the back. It also has a 5VDC "battery" jack to...

When I first got the HRDB, I couldn't hear much difference when I switched between the two PSs -- DPS and Astrodyne. Thus, I've been using the Astrodyne exclusively with the balanced setup and the DPS with the HRD-SE. About a week ago, however, on a whim, I decided to switch the DPS into the...

What's happening? Is it just by chance that so many RS-1s are suddenly up for sale? Or is there some flaw or problem we all need to be aware of? I was just thinking of an RS-1 or GS-1000 Black Dragon recabling for balanced.

Being blown away by my recent move to balanced, I thought I'd be gradually dumping my SE stuff (amps) or upgrading them (HPs) to balanced. But, despite the bliss with balanced, I'm still clinging to my SE equipment and feeling less anxious by the day about going completely balanced. In fact, I...

Here's something I stumbled on in eBay a few minutes ago. The seller is Otaku Cyber Convenience Store, apparently out of China. Feedback of only 9 sales (as of 16 May 2007) so no real track record. Appears legit. Check out the rest of this seller's eBay store. (Disclaimer: I'm in no way related...

In the next month or two, I'm going balanced, and I'm torn between the GS-X and the HeadRoom Desktop. Anyone have a chance to compare the two? In terms of footprint, the HRD is smaller and would fit right in with my present SE HRD with PSU. The GS-X is a little bigger, but I can accommodate...

Any of you with the X-Fi Elite Pro experiencing problems with the analog inputs in the back of the console? I've plugged in different components such as turntable, CD player, cassette deck. The problem is that I can't hear the sound that's coming in although it's registering in the Creative...

With talk of dedicated DACs in the Little Dot 2+ threads, I decided to revisit the DAC in the X-Fi Elite Pro PCI card. Here's the lineup I'm futzing with: Foobar2000 v0.9.4.2 > X-Fi Elite Pro PCI card > Y-cable > Little Dot 2++ > Black Dragon > GS1000 I decided on the 2++ to avoid the 2+'s...
