I would like share my current journey with my Liquid Platinum amp. Got this amp new. First tube I rolled was a pair USN-CEP 6922. Nice improvement from the stock tubes, but I was not completely happy with them for some reason - they sounded great but the wow factor was not there on this amp...

The Zhaolu came in two flavors - 2.5C and 2.5A. I prefer the 2.5A as the more musical version. YMMV. ripped out the head amp and analog section. It now houses separate PSU's for DAC and analog stage. upgraded the resistors on the zapfilter shunt PSU from 5W to 20W the 2.5A is balanced from...

  been enjoying my HD650 with my LD6 from some time now. . However, orthos got me REALLY interested. So I got myself a ROC to try. but I could not find anyone close by with either the Audeze or hifiman balanced orthos to try out and compare. I have briefly listened to the HE5 with my LD6 and...

is not really a 6SL7 but rather a substitute.... Been rolling VT-229 types for a while now. tried various 6SL7 brands, 6SU7 and ECC35 as well. Mullards are lush and nice but falls on speed and prat. Next on the ladder is 6SU7, mostly made by Tung Sol. Nice prat but can get easily fatiguing...

Just finished a few albums of this group. nice beats. But man, those lyrics. definitely rated R regardless, brilliant messages (you have to take the opposite direction, of course - it's like they tell you what NOT to do)

check out this link and follow the instructions. post your results creeping-up sound

I'd had several cables on balanced configuration and one thing I've noticed is that the performance difference between stock HD650 cables and premium ones is NOT as striking as when they are configured on SE. I've tried Cardas and ALO vs stock wires - the differences are there but not...

I've read about adding 100 ohms to each channel of the HD800 when plugged in to a Phoenix amp. The reason I read is b/c the output impedance on the amp is too low. Can someone explain the reasoning behind this? How was the resistor value derived? Is this "formula" applicable to other cans or...

MSRP of $500. At BEST, this is cat6 cable. case closed.

I currently have a zapped zhaolu 2.5c with XLR and RCA outputs. love the sound - lots of detail and very quiet. feeds my LD VI and it's a good match IMO. Just looking to see what you think will be a natural progression in terms of upgrade down the road..... prefer to get RCA and XLR outputs...

So I took the plunge…. I was very happy with my Extreme but I could just not get the thought of going balanced out of my head. My cans are HD650, which everyone says respond nicely to balanced configuration. My DAC already has true balanced output. So I figured “why not?”…. First a quick...

trying to pass some time so I opened up the cover and started re-wiring: changed the 5W wirewound on the ZF PSU to 10W units - the stock wirewound gets too warm for comfort changed out the wiring to solid core twisted pairs changed grounding to common source the sound? noticed that...

I know I should be happy and I am... great sound coming from my current rig: Zapfiltered Zhaolu 2.5C on RCA and XLR outs HD650 on SE cardas amp is SP Extreme on 6F8G and 5998 keeping the source and cans, will the stock LD VI be an improvement? hoping that someone here would have...

Remember this?

tried to put together some 6AS7G equivalents with notes (from my personal experience). of course, the usual brand/re-label disclaimers apply. So no need which one is better. The goal here is just to list the main equivalents that may work in your amp's circuit. Did I miss any equivalents...

for the record, I am not complaining.. BEACHAUDIO $590 B&H $595

I've always wondered about going balanced - Has anyone compared a really nice SE (SP extreme in this case) vs an equally good balanced setup (LD mk VI) I don't want to balanced for the sake of going balanced unless there is an improvement vs the Extreme. TIA.

stumbled across this. It's a 26-bit and 22,580khz sampling DAC. Balanced tube stage. From their site: This is one of our state-of-the-art designed D/A converters having a resolution of 26 bits and a 22,580 Khz (44.1Khz x 512= 22.58Mhz) re-sampling frequency that can completely eliminate...

Here's a dilemma: I have a Franken Zero (see the thread in the DIY section for reference) HDAM'ed, bypassed, modded - the works. And it's really great - I've had the Keces 151, Musiland MD10, Yulong, Lite AH - the Frankie really outshines them and sounds more musical to me. The OMZ...

So, what can we expect from a tube amplifier worth US $55,000 per pair? Obviously, an unrivaled blend of power and performance. The NAT Audio Magma tube amplifier is billed as the most powerful single-ended tube amplifier on the market. It throws 160 watts of pure power in the 10-10,000 Hz...

is this correct? I would think that it would not need further amp modification... so can I feed the (+), gnd and (-) of one balanced channel to the (R), gnd and (L) of a stereo amp? of course, I would need a second stereo to feed the other balanced channel
