Months ago I built a DIM (do it myself) TVC with TX102 MKIII (remember we have some little problem?
) ; one RCA in/one RCA out. Unfortunately one of my Monarchy Audio's SE100delux Class A mono amps Kaput! I had to wait all this time for the parts to arrive. Finally, I managed to repair it five days ago and obviously I connected them to my pre.
Firts impressions were similar to everything that has been said about them: VERY TRANSPARENT AND DETAILED, with acoustic instruments sounding very real and uncoulored; fast responses; very extended HF although my amps have "only" 33Kohm/1.7V at input; voices, both male and female, are breathtaking (class A amps). The bad news is that it sounded a bit thin and light, without bottom end. Cold, I might say.
I let them playing constantly, by day, and the sound is improving: music is rounder, softer, more laid back, but retains its detailed presentation (very hard to explain). LF armonics are a bit better and LF extension is decent now and very controled. I changed a DIY IC based on DH Labs Pro-audio cable (silver/copper) for a $1 copper IC and what is lost in resolution is gained in warmth (IC from DAC to pre is PSAudio Statement wich is a "fat" sounding cable). My view is that silver is not good for this pre (at least in my system).
I think that maybe the TX weren't "burned-in" as I had to wait for a shipment from England due to lack of stock.
If I ever get great bass (burning-in; changing cables or amps) this pre will be unbeatable!
The immediacy it brings to the records is outstanding
. This explain why it is so hard to comme back to active pre. Who would accept all this extra noise from an active stage?
A question arrises: what to do with the unused "+6db" primaries?
Also, I have "floating" ground at input and at output. I checked once with output grounded and I didn't hear any change. I will try again.
I also tried reversing input polarity but only got noise.
I'm trying to build a 4 channel classD amp with UcD180 modules from Hypex.nl. I hope everything goes OK to power speaker in active way.
