  1. Upgrade to T2  :)
  2. I don't know if there is some XLR to RCA converter that can make the RCA output 4V rms if the the XLR input is 4V rms
  3. Use an active preamp


4. 2v being *the* standard for RCAs... just don't bother ;p

Hi there,

Which is the better option for my Lumin T1, in terms of sound quality:

1. Lumin --> preamp --> power amplifier

2. Lumin --> power amplifier through XLR and use Leedh as digital volume control

I need your advise before upgrading my system and looking forward your information.

Thank you very much.

Francis

I've always been one that believes the shortest, most direct path be it with audio or "as the crow flies" is the best choice.

 

Of course if you need the preamp for equalization, switching functions, etc. than the preamp is the only way to go.

 

I've got my X1 going via XLR through an XLR switch to the input of the amplifiers so I can enjoy the best of both worlds by going direct when I use the X1 or going through the preamp / processor when I need the home theater setup.

 

But, PLEASE, don't let this sway you in any way into how to spend your money.  Only your decision and no one else's, other than maybe that of your significant other or your banker, should do that.

Which XLR switch are you using? I am doing something similar using RCA switching with a Manley Skipjack, but may need to look at using the XLR outputs of my A1 to have more output voltage so I have a broader choice of amps I can choose since the RCA outputs are only 2VRMS max

I am using the Kramer VS-4X.  It's passive and well-built.  I contacted Manley and they will probably never manufacture an XLR version of their switch and that's too bad.

I agree with you regarding the shortest path. As I mentioned in an earlier post, some albums require  the extra gain from a preamp. I don’t know if it is  just my system, but I am curious how Jonas Starker Bach cello Mercury label sounds direct to the amp. For me, direct just can’t produce the volume. Let me know.

Hello, some questions (I currently have a U1 mini):

-Would it be possible to add Deezer Hifi / Elite to the lumin app ?

-where to find the new (IR) remote in Europe?

-is Chromecast built-in possible?

-1. upsampling and 2. transcoding to DSD is nice, would it be possible to add an 5-band EQ, and/or a compressor for basic room correction in-between 1. and 2. ?

 

Cheers

There is no such truth. Music experience has a lot of personal influence that are not the same between us. My general experience is that a good preamplifier contributes to sound signature that you like or dislike. It also has other features to connect other sources. I use VTL TI 6.5 and I will not replace it. I chosed between VTL and Audio Research and VTL was more to my taste. Others do the opposite, so who is rigtht? Then you have the speakers, the room and your music taste to bring into the equation. You do not listen to Lumïn T1, you are listening to a system that play together.

 

My advice is to try find a dealer where you can do the test and to let your own ears decide what is best for you.

Sorry but I don't know or have access to that piece of music but I personally have had no experiences I can recall from having less than enough system volume going directly from the X1 (XLR) into the front end of the mono amps as attested to by knocks on the door by my neighbors and, on occassion, the local gendarmes and the protestations coming from my significant other two floors above.

 

My amplifier's input sensitivities are rated at 2.45V unbalanced and 4.9V balanced for 1200W (30.8dbW) output.

 

I use the Telarc offerings of "Bolero" and the "1812 Overture" and a version of Ralf Vaughn Williams "The Lark Ascending".  With Bolero, in particular, I have to crank the volume well above normal to properly enjoy the opening stanzas and, unless I ride the gain near the end, that's when the neighbors complain.
