Audio Horizons TP 2.0 Preamplifier

Gandme,
Joseph will do some very nice things to your TU-919. The Blackgate caps he puts in the power supply and signal path will need some break-in time, but in a short while, you might just be listening more to your tuner than your Cd player. It happened to me. Keep us posted.

I forgot to mention that much later, after Joseph had upgraded my tuner, I put some Blackgates in the MPX section of my tuner and it made another huge improvement. I have a 1977 Harman/Kardon Citation Eighteen tuner so the circuit could be a little different than the Sansui TU-919, but you might run the MPX upgrade question by Joseph. He offers several cost upgrades to tuners.

Hey Guys:
Well I finally got my AH DAC 3.0 back. The upgrade took much longer than I expected. Been playing it non-stop this weekend and want to give my initial impressions. As I indicated in earlier posts this is the Clarity-Vishay upgrade with harmonic alignment. The same one some of you are looking to apply to you AH preamps. This is not a review! I would never attempt to do that with my level of knowledge so please bear with me on this.

Just a few background notes:

I purchased the dac used from Grannyring about a year ago. My goal was to add some tube warmth and body to my all solid state system. My speakers are somewhat bright and forward sounding and my listening room amplifies these problems. Seemed like a good fit after chatting at length with Bill. The dac had upgraded, warmer sounding tubs so I went for it. The stock unit met my goals and expectations and then some. Just to nitpick a little I always thought the presentation was a little odd or different.

So right out of the gate I could tell the sound was much smoother and refined. There appears to be a film or haze that has been lifted and clear, detailed, wonderful music has emerged. The thing I like best is you can enjoy these new attributes at much lower listening volumes. Also, that presentation issue is a thing of the past. Perfect balance! From what you all are saying the best has yet to come keeping in mind I only have about 10 hrs of break-in time so far.

I’ll report back in a few weeks.

Great news, Charlie. I look forward to hearing more of your impressions as the unit goes through its break-in process. I'm thinking it will only get better.

Charlie, glad to hear that without any burn in you love the upgraded DAC. That is a great DAC and I am sure it is now something very special.

I have an idea for you if your amps are on the floor. Place them on Sistrum SP 004 stands and then place about 2 pounds of clean sand in a nice zip lock bag and place on top of your amp. The Sistrum stands the 003's or 004's can be had for about $150 each used.

Now listen to your system. Wait until you have some 200 hours on the DAC before doing this amp tweek. You will be very pleased!
